摘要

PURPOSE:To obtain the titled composition having remarkably reduced evaporation residue without decreasing the plasticizer, prolonged decomposition time, and improved gelation property and tackiness, by compounding a monomeric secondary plasticizer with an aliphatic polybasic acid polyester plasticizer. CONSTITUTION:100pts.wt. of a polyvinyl chloride is compounded with 10-50pts. of a monomeric secondary plasticizer and 1-50pts. of an aliphatic polybasic acid polyester plasticizer. The monomeric plasticizer is preferably an aliphatic dibasic acid ester, a polybasic hydroxycarboxylic acid ester, a fatty acid ester or their combination. The polyester plasticizer is those containing an aliphatic polybasic acid and a polyhydric alcohol as essential components.
