The invention relates to tetrachloroethyl esters of unsaturated organic acids of the general formula I ##EQU1## WHERE X stands for a substituent selected from the group consisting of COOH, COOCH.sub.3, COOC.sub.2 H.sub.5, ##EQU2## It further relates to their polymers and mixed polymers of the above monomers, namely with vinyl and diene compounds, and to methods for preparation both monomers and these polymers. To prepare the compounds of the general formula I, acyl chloride of the general formula II ##EQU3## where Y stands for a substituent selected from the group consisting of COOH, COOCH.sub.3, COOC.sub.2 H.sub.5, ##EQU4## is treated with chloral, advantageously in the presence of a mineral acid or salt, for example with addition of sulfuric acid and ferric chloride, respectively.
本发明涉及一般式I的不饱和有机酸的四氯乙酯,其中X代表从COOH,COOCH.sub.3,COOC.sub.2H.sub.5,##EQU2##等基团中选择的取代基。还涉及上述单体的聚合物和与乙烯和二烯化合物的混合聚合物,以及制备这些单体和聚合物的方法。为制备一般式I的化合物,一般式II的酰氯##EQU3##其中Y代表从COOH,COOCH.sub.3,COOC.sub.2H.sub.5,##EQU4##等基团中选择的取代基,经过氯化醛处理,优选地在矿物酸或盐的存在下,例如加入硫酸和三氯化铁。
