PURPOSE:The titled compsn. prepared by blending a plasticizer, a heat stabilizer, etc. into a copolymer of polyethylene glycol di(meth)acrylate and vinyl chloride and providing molding products free from oozing-out of the plasticizer. CONSTITUTION:A vinyl chloride copolymer is prepared from 0.05-5.0wt% polyethylene glycol di(meth)acrylate of formulaIor II (wherein n is 2-100) and 99.95-95.0wt% vinyl chloride, and then a plasticizer (e.g. di-n-octyl phthalate, di-2-ethylhexyl adipate), a Ca-Zn bared heat stabilizer (e.g. calcium stearate, zinc palmitate) and an epoxy plasticizer (e.g. epoxidized soya bean oil) are blended into the copolymer.
