Abstract

Procedure for the preparation of polymers based on vinyl chloride, in an aqueous medium in the presence of an initiator system composed of an organic peroxide and a reducer, characterized in that the aqueous medium does not contain an emulsifier, because the monomer is continuously introduced into a pressure lower than its saturating vapor pressure, because said organic peroxide is introduced by means of a previously prepared polyvinyl chloride-based seed product, because the reducer is introduced continuously or in parts during the entire polymerization operation and by that the polymerization operation is also carried out in the presence of a coagulating mineral salt of the latex.
