Abstract
The rheological properties of paste-formable, powdered polymerizates produced by polymerizing vinyl chloride or a mixture of vinyl chloride and a copolymerizable monomer in an aqueous emulsion in the presence of a water-soluble catalyst and an alkali metal salt of a fatty acid as the polymerization emulsifier and spray drying the resultant polymerizate, are improved by treating the powdered polymerizate with a gas which forms an acid in an aqueous solution.
