1-Aryl-2,2,2-Trichloroethyl esters of acrylic and methacrylic acid and their polymers

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 radic...

Description
Summary: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. 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.
