    Description / Table of Contents: 1-Aryl-2,2,2-trichlorethyl-acrylate und-methacrylate wurden hergestellt, bei denen die Arylgruppe Phenyl-, 4-Chlorphenyl-, 4-Bromphenyl- oder 2,5-Dichlorphenyl war. Durch radikalische Polymerisation mit AIBN wurden die Ester zu harten, transparenten Blöcken oder in benzolischer Lösung polymerisiert. Von den Polymeren wurden die Dichte, die Zersetzungstemperatur, die Glastemperatur und der Sauerstoff-Index für selbständiges Verbrennen bestimmt.
    Notes: Acryloylation and methacryloylation of 1-aryl-2,2,2-trichloroethanol were used in the preparation of (1-aryl-2,2,2-trichloroethyl) acrylates and methacrylates, respectively, in which the aryl groups were represented by the phenyl, 4-chlorophenyl, 4-bromophenyl, and 2,5-dichlorophenyl group. By radical polymerization using 2,2′-azobis(isobutyronitrile), the esters were polymerized to hard transparent blocks or in benzene solution. The density of homopolymers, the temperature of their initial decomposition, the glass temperature and the limiting oxygen index of their continuous flaming combustion were determined.

    Description / Table of Contents: Es wurde die Hydrolyse einer Reihe von Methacrylaten in einer 2,5proz. wäßrigen alkoholischen Lösung von Natriumhydroxid bei 25°C untersucht. Die Hydrolyse der Estergruppe in 2-(N-Methylanilino)ethyl-(III), 3- und 4-Dimethylaminobenzyl-(IV,V), 2-Carboxyphenyl-(VI) und 2,2,2-Trichlorethyl-(VII)methacrylat schreitet mit nahezu derselben Geschwindigkeit fort wie in Methylmethacrylat (I) und Dimethylaminoethylmethacrylat(II); innerhalb 25 min waren etwa 80% des ursprünglichen Esters hydrolysiert. In alkalischen Lösungen von 1,2,2,2-Tetrachlorethyl-(VIII), 2-(1,2,2,2-Tetrachlorethoxy)ethyl-(IX) und 1-(4-Chlorphenyl)-2,2,2-trichlorethyl(X)methacrylat nimmt die Geschwindigkeit der Hydrolyse der Estergruppe in der Reihenfolge VIII〉IX〉X ab. Die Hydrolyse der Estergruppe wurde durch die Geschwindigkeitskonstante 2. Ordnung charakterisiert.
    Notes: The hydrolysis of a number of methacrylates in a 2,5% water-alcoholic solution of sodium hydroxide at 25°C was investigated. The hydrolysis of the ester group in 2-(N-methylanilino)ethyl(III), 3- and 4-dimethylaminobenzyl-(IV, V)-2-carboxyphenyl (VI) and 2,2,2-trichloroethyl (VII) methacrylate proceeded at approximately the same rate as in methyl methacrylate (I) and dimethylaminoethyl methacrylate (II); within 25 min, some 80% of the original esters were hydrolyzed. In alkaline solutions of 1,2,2,2-tetrachloroethyl (VIII), 2-(1,2,2,2-tetrachloroethoxy)ethyl (IX) and 1-(4-chlorophenyl)-2,2,2-trichloroethyl(X) methacrylates, the rate of hydrolysis of the ester group is decreasing in the order VIII〉IX〉X. The hydrolysis of the ester group was characterized by the rate constants of second order.

    Notes: The copolymerization parameters of 2-acryloyoxybenzoic (AOB) and 2-methacryloyloxybenzoic (MOB) acids, methyl 2-methacryloyloxybenzoate (MMOB), and N-methyl-N-phenyl-2-aminoethyl methacrylate (MPAM) with styrene in benzene solution were determined and used in the calculation of the Alfrey-Price copolymerization constants e and Q for AOB, MOB, MMOB, and MPAM. Using e Q thus determined and the corresponding tabulated values for methacrylic acid (MAA), the copolymerization parameters of pairs AOB-MPAM, MOB-MPAM, MMOB-MPAM, and MAA-MPAM were calculated. They are compared with those determined by the copolymerization of these pairs in which the interaction of functional groups on comonomers plays a role.

    Notes: 3- and 4-dimethylaminobenzyl acrylates (3 and 4) and methacrylates (1 and 2) were prepared and their densities, IR and NMR spectra are recorded. In order to evaluate their reactivity towards benzoyl peroxide, the rate constants of the reaction of benzoyl peroxide with 3- and 4-dimethylaminobenzyl alcohols and 3- and 4-dimethylaminobenzyl acetates were determined. The reactivity of the esters prepared in this work appeared to be weaker than that of an N-aryl-N-alkylaminoalkyl methacrylate. The blocks of homopolymers of these esters and of their copolymers (mole ratio 1:1) with styrene and methyl methacrylate are crosslinked. Both homopolymers and copolymers of 1 and 3 are more stable in polar solvents and on heating than polymers of 2 and 4. The copolymerization parameters of 1 and 2 with styrene are close to the copolymerization parameters of methyl methacrylate with styrene.

    Notes: The polymerization rate (Rp) of N-methyl-N-phenyl-2-aminoethyl methacrylate (MPAEMA) initiated with 2,2' -azodiisobutyronitrile (AIBN) at 50°C increased considerably after the addition of CCI3COOH, and distinctly after the addition of CH3COOH. Rp in a benzene solution of 2 mol. dm-3 MPAEMA and 5 · 10-2 mol. dm-3 CCl3COOH (without AIBN) was 13% · h-1. [η]DMF20 of the obtained polymer corresponded to 64 cm3 · g-1. The polymerization order of MPAEMA initiated with CCl3COOH is 0,93 with respect to monomer and 0,51 with respect to CCl3COOH. The overall activation energy of polymerization of MPAEMA calculated from the temperature dependence of Rp between 20 and 50°C is 43 ± 1,2 kJ · mol-1. In a benzene solution of 2 mol.dm-3 MPAEMA, 5 · 10-2 mol · dm-3CCl3COOH and 5 · 10-3 mol · dm-3 1,4-benzoquinone at 50°C the polymerization does not proceed for 6 h. In a benzene solution of 2 mol · dm-3 4-dimethylaminostyrene (4-DMAS) and 2 mol · dm-3 CH3COOH (without AIBN), 40% of monomer polymerized within one hour. [η]DMF20 of the polymer was 4 cm3 · g-1. The overall activation energy of polymerization of 4-DMAS in the presence of CH3COOH is ca · 54 kJ · mol-1. The addition of 5 · 10-3 1,4-benzoquinone slows down the polymerization rate only slightly. The effect of acids on the elementary polymerization reactions is characterized.

    Description / Table of Contents: A series of new 2-(N-aryl-N-methylamino)ethyl methacrylates (2a-f) was synthesized. They may serve as polymerizable components in the initiation system diacyl peroxide/tertiary amme. Their physical properties, as density, refractive index, boiling point, NMR, and IR spectra, were determined. During the reaction with benzoyl peroxide the amines were transformed into gel-polymers. To determine the reactivity of these monomers towards peroxide, the rate constants of the reactions between benzoyl peroxide and the 2-(N-aryl-N-methylamino)ethanols 1a-f and between benzoyl peroxide and 2-(N-methyl-N-phenylamino)ethyl isobutyrate (3) were measured. Bulk polymerization of the unsaturated tertiary amines prepared was also corroborated.
    Notes: Eine Reihe neuer 2-(N-Aryl-N-methylamino)äthylmethacrylate (2a-f) wurde synthetisiert. Die Verbindungen konnten als polymerisierbare Komponenten der Initiierungssysteme Diacylperoxid/tertiäres Amin benutzt werden. Ihre grundlegenden physikalischen Eigenschaften wie Dichte, Brechungsindex, Siedepunkt, NMR- und IR-Spektren wurden bestimmt. Bei der Umsetzung mit Benzoylperoxid wandelten sich die Verbindungen 2a-f in Gel-Polymere um. Zur Beurteilung ihrer Reaktivität gegenüber Peroxid wurden die Geschwindigkeitskonstanten der Reaktion des Benzoylperoxids mit den als Ausgangsverbindungen dienenden 2-(N-Aryl-N-methylamino)äthanolen 1a-f und dem nicht polymerisierbaren Modell der Aminoäthylmethacrylate, dem 2-(N-Methyl-N-phenylamino)äthylisobutyrat (3), bestimmt. Auch die Substanzpolymerisation der dargestellten ungesättigten tertiären Amine konnte bestätigt werden.

    Notes: The copolymerization parameters of N-methyl-N-phenyl-2-aminoethyl methacrylate (MPAM) and 2-acryloyloxybenzoic (AOB), 2-methacryloyloxybenzoic (MOB), and methacrylic acid (MAA) with styrene in DMSO solution at 50°C were determined and used in the calculation of the Alfrey-Price copolymerization constants e and Q for MPAM, AOB, MOB, and MAA. From the e and Q constants of the monomers thus determined, the copolymerization parameters of the pairs MPAM-AOB, MPAM-MOB, MPAM-MAA were calculated and compared with those determined by the copolymerization of the corresponding pairs in DMSO.

    Notes: Some simple equations for the emulsion polymerization system were derived on the basis of the Smith-Ewart theory. These are used in calculating the molar monomer concentration and rate of polymerization in units of moles per liter per second for the zero-order region with respect to the monomer as well as in calculating the rate constant of the growth reaction.
