Abstract
Homopolymers and copolymers of vinyl chloride containing at least 85 % by weight of polymerised vinly chloride units are prepared continuously in aqueous emulsion. The polymerisation is carried out in the presence of water-soluble catalysts which form free radicals, polymerisation auxiliaries and 1.5 to 3 % by weight of an emulsifier mixture. The emulsifier mixture comprises a) alkali metal and/or ammonium salts of sulphosuccinic diesters and b) alkali metal and/or ammonium salts of alkylsulphonic acids and/or of alkylarylsulphonic acids of the type and composition defined in Claim 1. The dried polymers obtained are particularly suitable for the preparation of plastisols.
