MANUFACTURE OF PASTABLE POLYMER OF VINYL CHLORIDE

Japanese Patent JPS59100113

A

1. A process for the production of a pastable polymer of vinyl chloride or of a mixture of vinyl chloride with up to 30% by weight of copolymerisable monomer by discontinuous polymerisation in the presence of a water-soluble catalyst, an emulsifier and a long-chain alcohol, characterised in that an emulsifier system composed of a) an alkali metal or ammonium salt of a branched or unbranched fatty acid of 12 to 18 carbon atoms, of a branched or unbranched alkylsuphonic acid of 10 to 20 carbon atoms, of an alkylarylsulphonic acid of 8 to 18 carbon atoms in the alkyl chain, which is branched or unbranched, or of a sulphosuccinic acid ester of 6 to 14 carbon atoms in the alcohol moiety, the salt being used in an amount of 0.2 to 3.0% by weight, based on the monomer content, b) a straight-chain or branched C12 to C20 alkanol, the alkanol being used in an amount of 50 to 200% by weight, based on the surfactant added, and c) water is homogenised by means of a homogenising machine and is subsequently mixed with vinyl chloride or with a mixture of vinyl chloride and the copolymerisable monomer(s), after which the mixture is subjected to a polymerisation reaction.
