    Notes: Polymerization of Vinyl Compounds in the Presence of Titanium(III)ChlorideThe polymerization of styrene, acrylonitrile and some methacrylates initiated by a titanium(III) chloride dichloroacetic acid redox system was studied. The monomer selectivity of the polymerization in the presence of titanium(III) chloride was found to be affected by a reductive termination reaction. Titanium(III) chloride acts as a retarder in the polymerization of styrene initiated by azobisisobutyronitrile (AIBN). The polymerization of polar monomers like acrylonitrile, methyl, ethyl and propyl methacrylate by AIBN is inhibited by titanium(III) chloride.

    Description / Table of Contents: Chlorinated polypropylenes with a chlorine content between 3 and 72.3% by wt. as well as chlorosulfonated polypropylenes with a chlorine content between 3 and 54.4% by wt. and a sulfur content between 1.2 and 5.9% by wt. are prepared by means of chlorination and chlorosulfonation of atactic polypropylene in solution. The influence of substitution von molecular weight, intrinsic viscosity, glass transition temperature as well as dynamic-mechanical behaviour and thermal short-time behaviour of the polymers is investigated.
    Notes: Durch Chlorierung und Sulfochlorierung von ataktischem Polypropylen in Lösung werden gezielt chlorierte Polypropylene mit 3 bis 72,3 Masse-% Chlor und einem Schwefelgehalt von 1,2 bis 5,9 Masse-% dargestellt. Es wird der Einfluß der Substitution auf die rel. Molekülmasse, Grenzviskosität und Glasübergangstemperatur sowie das dynamisch-mechanische Verhalten und das thermische Kurzzeitverhalten der Polymere untersucht.

    Description / Table of Contents: Using the managers(IV)-method methyl methacrylate was grafted onto potato starch and dextran as well as 1-acryloyl-3-methylpyrazole and 1-methacryloyl-3,5-dimethyl-pyrazole onto potato starch. The graft copolymerization of potato starch with methyl methacrylate was investigated with respect to the influences of the acid concentration, the solvent composition, the presence of permanganate, and the gelatinization of starch.
    Notes: Nach der Mangan(IV)-Methode wurden Methylmethacrylat auf Kartoffelsärke und Dextran sowie 1-Acryloyl-3-methyl-pyrazol und 1-Methacryloyl-3,5-dimethyl-pyrazol auf Kartoffelstärke gepfropft. Für die Pfropcopolymerisation von Kartoffelstärke mit Methylmethacrylat wurde der Einfluß der Säurekonzentration, der Lösungsmittelzu sammensetzung, der Anwesenheit von Permanganat und der Gelatinierung der Stärke untersucht.

    Description / Table of Contents: The procedure of the quantitative microstructure analysis from the 13C{1H}-PFT-NMR spectra of a series of chlorinated atactic polypropylene samples is described. Intensity correction factors are derived. Following microstructure parameters are obtained from the assigned and corrected resonance intensities (areas): total degree of chlorination ασ per monomeric unit.mole fractions of all initial and derived (chlorinated) groups.degrees of chlorination α(CH), α(CH2), α(CH3) of the different groups,ratio of the averaged chlorination probabilities p̄(CH): p̄(CH2): p̄(CH3) of the (C—H)-bonds in the groups considered, which is a measure of the mean relative reactivity of the (C—H)-bonds in these groups.Additionally the mole fraction of (—CHCl2)-groups can be tested by combination of the obtained 13C-NMR-results with 1H-NMR measurements.
    Notes: Die Methodik der quantitativen Mikrostrukturanalyse aus den 13C—{1H}—PFT-NMR-Spektren einer Serie von chlorierten ataktischen Polypropylenproben wird beschrieben. Intensitätskorrekturfaktoren werden abgeleitet. Aus den zugeordneten, korrigierten Resonanzintensitäten (Flächenauswertung) lassen sich folgende Mikrostrukturparameter quantitativ bestimmen: der summarische Chlorierungsgrad ασ pro Monomereinheit,die Molanteile aller unchlorierten (Ausgangs-) und chlorierten Gruppen,die Gruppenchlorierungsgrade α(CH), α(CH2), α(CH3),das Verhältnis der mittleren Chlorierungswahrscheinlichkeiten der (C—H)-Bindungen in den Gruppen p̄(CH) : p̄(CH2) : p̄(CH3), das ein Maß für die mittlere relative Reaktivität der (C—H)-Bindungen in den Gruppen darstellt.Zusätzlich kann durch 1H-NMR-Messungen in Kombination mit den erhaltenen 13C-NMR-Ergebnissen der Molanteil der (CHCl2)-Gruppen überprüft werden.
