<p>A vinyl chloride resin composition which is reduced in plate-out generation on metallic surfaces of a molding machine without impairing the properties and appearance of a product and has excellent moldability. The composition is obtained by compounding 0.3 to 50 parts by weight of a crosslinked polymer (I) with 100 parts by weight of a vinyl chloride resin. The polymer (I) has a volume-average particle diameter of 10 to 1,000 nm and is obtained by polymerizing a monomer mixture which comprises 50 to 98 parts by weight of a monomer ingredient (A) consisting of 60 to 100 wt.% at least one monomer selected among methacrylate monomers, acrylate monomers, vinyl cyanide monomers, and aromatic vinyl monomers and 0 to 40 wt.% other vinyl monomer(s) copolymerizable therewith (the sum is 100 wt.%) and 2 to 50 parts by weight of a polyfunctional monomer ingredient (B), the sum of the monomer ingredients (A) and (B) being 100 parts by weight, in the presence or absence of an elastic polymer, and in which the monomer ingredient excluding the polyfunctional monomer, when polymerized, gives a polymer having a glass transition temperature Tg of 20°C or higher.</p> |
