ABSTRACT:
A plasticized vinylidene chloride-vinyl chloride copolymer is produced by copolymerizing 65 to 95 wt. % of vinylidene chloride and 35 to 5 wt. % of vinyl chloride or a mixture of vinyl chloride as a main component and a comonomer wherein 0.5 to 10.0 wt. parts of a plasticizer being soluble in said monomer mixture is added to 100 wt. parts of said monomer mixture and said monomer mixture is copolymerized by a suspension polymerization in the presence of an oil soluble radical initiator and a macromolecular suspending agent in water whereby a blending step can be eliminated.
