ABSTRACT:
The invention relates to tetrachloroethyl esters of unsaturated organic acids of the general formula I ##STR1## where X stands for a substituent selected from the group consisting of COOH, CCOCH.sub.3, COOC.sub.2 H.sub.5, ##STR2## 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 ##STR3## where Y stands for a substituent selected from the group consisting of COOH, COOCH.sub.3, COOC.sub.2 H.sub.5, ##STR4## AND ##STR5## 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.
