    Preparation and properties of polyester-urethane block copolymers (1961)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Polyester-urethane block copolymers were prepared by the block polyaddition reaction of diisocyanate with two kinds of linear polyesters, one of which was polyethylene terephthalate. The melting points of polyester-urethane block copolymers containing more than 30% polyethylene terephthalate are independent of the total molar fraction of the two polyester components, so that the melting point-composition curves are step-shaped. The relation between the second-order transition point of the block copolymer and its composition, on the other hand, is the same as that for a random copolymer. It is observed that some polyester-urethane block copolymers containing 15-50% of polyethylene terephthalate have elastic properties. For example, the 15/85 polyethylene terephthalate/polyethylene adipate-tetramethylene diisocyanate block copolymer has a tensile strength of 240 kg./cm.2 and an elongation of 700%. It may be supposed that these elastic properties are due to the structure of the block copolymer chains: the flexible polymer chains in the amorphous region may be joined to the crystallites of polyethylene terephthalate, so that a type of network structure similar to crosslinking is formed.

    Description / Table of Contents: Als ein Weg zur Darstellung reaktionsfähiger Makropolymerer wurde die Copolymerisation des Acrylnitrils mit Glycidylmethacrylat und Glycidylacrylat untersucht. Die dargestellten Copolymerisate sind löslich, formbar und spinnbar.Die homogene Reaktion der Copolymeren mit Aminen in Dimethylformamid und die heterogene Reaktion von Fäden der Copolymerisate mit Aminen, Aminosäuren und Farbstoffen mit Amino- und phenolischen Hydroxygruppen wurden ausgeführt. Nach den Ergebnissen stellt das Copolymere aus Acrylnitril mit Glycidylmethacrylat ein sehr reaktionsfähiges Polymeres dar.
    Notes: As one of the ways to obtain high molecular compounds which have chemical reactivity, the copolymerizations of acrylonitrile with glycidyl methacrylate, and with glycidyl acrylate were examined to prepare the copolymers which are soluble, moldable and spinnable. The homogeneous reaction of the copolymers with amines in dimethylformamide and the heterogeneous reaction of the fibers from copolymers with amines, amino acids, and dyes containing amino, phenolic hydroxyl groups was carried out, and it was assumed that the copolymer of acrylonitrile with glycidyl methacrylate was a “Reactive Polymer” having considerable chemical reactivity.

    Description / Table of Contents: Ein neues Vinylmonomeres, Glycidylvinylsulfonate (GVS), das einen Epoxydring besitzt, wurde durch Kondensation von Vinylsulfochlorid mit Glycid synthetisiert. GVS (M2) wurde mit Styrol und mit Methylmethacrylat (M1) copolymerisiert; die Copolymerisationsparameter r1 und r2 wurden berechnet: r1 = 1,19, r2 = 0,03 mit Styrol und r1 = 14,4, r2 = 0,01 mit Methylmethacrylat. Die Q- und e-Werte betragen 0,21 und 1,0. Die Epoxydgruppe im Styrolcopolymeren reagiert mit Chlorwasserstoffsäure und Aminen wie die monomeren Epoxydverbindungen.
    Notes: A new vinyl monomer, glycidyl vinyl sulfonate (GVS) which had an epoxy ring was synthesized by condensation reaction of vinyl sulfonyl chloride and glycidol. GVS (M2) was copolymerized with styrene and methyl methacrylate (M1) and the monomer reactivity ratios were determined r1 = 1.19, r2 = 0.03 with styrene and r1 = 14.4, r2 = 0.01 with methyl methacrylate respectively. The Q- and e-values were 0.21 and 1.0 respectively. The epoxy group in the styrene copolymer reacted with hydrochlorie acid and amines like monomeric epoxy compounds.

    Notes: Polyaddition reactions between polymethylene bis-N,N-ethyleneurethanes and polymethylene dimercaptans were investigated. The most successful polyaddition was carried out in dimethylformamide at 75°C. in the presence of triethylamine as catalyst; a fiber-forming polyurethane sulfide having an intrinsic viscosity of 1.05 was obtained in about 90% yield. Arguments for the linear structure of the product are given.

    Description / Table of Contents: Aus Lävulinsäure und Furfurol als Ausgangsmaterial wurde in vier Stufen Diäthyl-1-methylpyrrolidin-2,5-di-β-propionat hergestellt.Durch Kondensation dieser Ester mit Hexamethylendiamin und/oder mit Hexamethylendiamin und Diäthyl-adipat, -azelat oder -sebacat wurden Homopolyamide und Copolyamide hergestellt. Ihre Darstellung und ihre Eigenschaften, wie Faserbildungsvermögen, Schmelzpunkte und Löslichkeiten, werden beschrieben.Einige Copolyamide wurden durch Schmelzspinnen in Fasern verwandelt, und der Einfluß der basischen Pyrrolidingruppe in der Kette auf die Eigenschaften der Fasern, besonders hinsichtlich der Anfärbbarkeit, wurde untersucht.
    Notes: Diethyl 1-methylpyrrolidine-2,5-di-β-propionate was prepared from levulinic acid and furfural as starting material through four steps.This ester was condensed with hexamethylene diamine to the homopolyamide and/or condensed with hexamethylene diamine and diethyl adipate, azelate or sebacate to the copolyamides. Their preparation and properties, such as fiber-forming properties, melting points, and solubilities, are described.Some copolyamides were converted to fibers by a melt-spinning process and the effect of the basic pyrrolidine group inserted in polymer chain on the fiber properties, especially on the dyeing properties, were studied.
