Abstract

1. A process for the manufacture of vinyl chloride homopolymers and vinyl chloride copolymers with at least 60% by weight of vinyl chloride units polymerized therein and, optionally, up to 40% by weight of monomer units copolymerizable with vinyl chloride in the presence of from 0,01 to 3% by weight, based on monomers, of free-radical initiators, emulsifiers in amounts of from 0,01 to 5% by weight, and/or protective colloids in amounts of from 0,01 to 3% by weight, based on monomers, and in the presence of a compound preventing polymeric deposits on the walls of the polymerization autoclave, at pressures of between 1 to 100 bar and temperatures of between -20 and 100 degrees C in an aqueous dispersion up to solids contents of between 10 and 60% by weight in a continuous and/or discontinuous polymerization, characterized in that for preventing polymeric wall deposits water-soluble polymers containing carboxylic acid groups, aldehyde groups and, optionally, hydroxy groups, are used.
