ABSTRACT:
A process for producing a powdery composite polymer, which comprises mixing in an aqueous medium (A) a particulate vinyl chloride polymer, (B) an elastomer containing a nitrile group and (C) a solvent for the elastomer (B) which is not miscible with water and is a poor solvent for the polymer (A), thereafter removing the solvent (C) from the mixture, and dehydrating and drying the mixture thereby to form a powdery composite polymer composed of the vinyl chloride polymer (A) and the nitrile group-containing elastomer (B).
