VINYL CHLORIDE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a vinyl chloride resin composition which exerts an extremely small change in its hardness caused by the change of temperature associated with the change of seasons, etc. SOLUTION: The vinyl chloride resin composition is prepared by compounding 100 pts.wt. vinyl chloride resin with from 15 to 100 pts.wt. plasticizer and from 10 to 200 pts.wt. copolymer containing from 20 to 60 wt.% methyl methacrylate monomer unit, from 10 to 60 wt.% acrylic ester monomer unit and from 1 to 20 wt.% styrene monomer unit as constituents.
