ABSTRACT OF THE DISCLOSURE: The invention relates to tetrachloroethyl esters of unsaturated organic acids of the general formula I: Image (I) where X means the groups CH=Ch2, Image , COC1, Image , and Image , and to their polymers, mixed polymers, namely with other vinyl and diene compounds, and to methodsfor preparation of both monomers of the general formula I and their homopolymers or mixed polymers These compounds of the general formula I can be produced, accor- ding to the invention, by treatment of n moles of acyl chloride of the general formula II: Image (II) where Y are groups CH=CH2, COC1 , or Image , with 0.5 to 2n moles of chloral. The pure components or their solution can be used for the above addition. The reac- tion is accelerated by addition of a small amount of acids, for instance, concentrated sulfuric or some salts. Because of the easy preparation of starting compounds of the general formula II and their moderate price, it may be assumed that acrylates and methacrylates with high content of chlorine prepared in this way will find their application as monomers and comonomers for prepa- ration of polymeric materials with suppressed flammability.
