PURPOSE:To obtain a nontoxic plasticizer for vinyl chloride based resins, consisting of a specific triglyceride compound and having excellent compatibility as well as plasticizing efficiency for the vinyl chloride based resins. CONSTITUTION:A plasticizer for vinyl chloride based resins consisting of a triglyceride compound expressed by the formula (R<1>-R<3> are 2-12C, preferably 6-10C fatty acid residue, and preferably at least one of R<1>-R<3> has a branched structure), preferably glyceryl tricaproate, glyceryl tricaprylate, etc., particularly preferably glyceryl tri-2-ethylhexanoate. The above-mentioned plasticizer is blended in an amount within the range of 5-60pts.wt., preferably 10-50pts.wt. based on 100pts.wt. vinyl chloride based resin (having 400-3,000, preferably 600-2,700, particularly 800-1,700 average polymerization degree). |
