PURPOSE:To obtain a vinyl chloride resin composition, excellent in transparency with prevented sticking to rolls in rolling, by blending a vinyl chloride resin composition containing a mixture of zinc mono- and distearyl phosphates blended therein and further a specific amount of specified fine silica powder. CONSTITUTION:A vinyl chloride resin composition obtained by blending 100 pts. wt. polyvinyl chloride with (A) 20-80 pts.wt. plasticizer (e.g., phthalic acid diester), (B) 0.02-3 pts.wt., preferably 0.1-2 pts.wt. metallic salt of a fatty acid (e.g., calcium 2-ethylhexylate), (C) 0.005-3 pts.wt., preferably 0.1-2 pts.wt. mixture of zinc distearyl phosphate with zinc monostearyl phosphate at 1:4-1:6 molar ratio and (D) 0.1-1 pt.wt., preferably 0.2-0.5 pt.wt. fine silica powder having <=200mum average particle diameter of primary particles and >=35wt.% silanol groups substituted by alkyl groups. |
