Abstract
Abstract A soft vinyl chloride resin composition having a light weight and a superior abrasion resistance and lusterless surface is provided, which composition is obtained by blending 100 parts by weight of a vinyl chloride copolymer consisting of 99.0 to 99.95% by weight of vinyl chloride and 1.0 to 0.05% by weight of a polyethylene glycol diacrylate or a polyethylene glycol dimethacrylate both having 4 to 50 polymerization units of ethylene glycol, mainly with (a) 5 to 100 parts by weight of a filler having a specific gravity of 0.7 or less and a compressive strength of 70 Kg/cm 2 or higher and (b) 30 to 150 parts by weight of a plasticizer.
