A method of producing suspension polymerized vinyl chloride polymers or copolymers of improved flowability by polymerizing vinyl chloride monomers alone, or in a mixture with other monomers, in an aqueous medium, to form a slurry of polymer suspended in said aqueous medium. After removing unreacted monomers, a polyhydric alcohol is added to the slurry containing the suspension polymerized polymer or to a product obtained after the dewatering of the slurry, in an amount of 0.001 to 0.5 parts by weight based on 100 parts by weight of the vinyl chloride polymer or copolymer suspended in the slurry.

Method of preparing vinyl chloride polymers and copolymers of improved

A material for the preparation of an internal-finishing skin of a composite type composed of a polyvinyl chloride and a polyurethane derived from reaction of a polyester polyol with an aliphatic or alicyclic diisocyanate, in which said polyesterpolyol comprising:

Internal-finishing skin material

A non-tacky composite resin composition comprises a polyurethane having a group represented by the general formula (I) in the molecule thereof, and a polyvinyl chloride, ##STR1## where Me is a methyl group, n is an integer of 1.ltoreq.n.ltoreq.100, X and Y are respectively an integer provided that 1.ltoreq.X.ltoreq.3, 0.ltoreq.Y.ltoreq.2, and X+Y=3, and R is an alkylene group or alkylene groups which may be linked by one or more alkyleneoxy groups.
