Abstract
Improvements introduced in the object of the Main Patent No. 243,944 by a polymerization process of vinyl chloride comprising a polymerization and/or copolymerization process of compounds containing at least one ethylenic double bond and corresponding to the general formula ** (See formula) ** wherein R1, R2, R3 and R4 represent hydrogen, saturated or unsaturated hydrocarbon radicals or polar atoms and/or groups such as halogens, ester groups, ether, hydrocarbon radicals substituted by halogens, at least one of which is groups R1, R2, R3 and R4 a polar group other than a hydrocarbon radical, excluding the -CN groupings, characterized in that the polymerization is carried out in the presence of a catalyst consisting of organic derivatives of boron corresponding to the general formula BR3 , R representing an alkyl radical.
