Abstract: Polyvinyl chloride (PVC) is generally used for phthalate plasticizers, because of its high plasticizing efficiency. These phthalate plasticizers will cause the problems of durability, toxicity and potential carcinogenicity, they can make service life shorter, endanger human and animal health. So it has been gradually replaced by the new type of plasticizer. Polyester plasticizer is a kind of green environmental protection plasticizer and can better solve the disadvantage of traditional plasticizer, so it was widely studied at home and abroad. In this article, plasticizing mechanism(Lubricity theory, Gel theory, Free volume theory), selection criteria, synthesis and classification of the polyester plasticizer are introduced. The polyester plasticizer is mainly divided into two categories:biological polyester plasticizer and petroleum polyester plasticizer.

摘要： PVC增塑剂以邻苯二甲酸酯类增塑剂为主,因其较高的增塑效率被广泛使用,但此类增塑剂耐久性差,使产品的使用寿命变短,具有毒性和潜在致癌性,影响人类及动物健康,已逐渐被新型增塑剂所取代。聚酯增塑剂是一种绿色环保型增塑剂,可以较好地解决传统增塑剂的缺点,所以被国内外广泛地研究,本文概述了聚酯增塑剂的增塑机理(凝胶理论、润滑理论和自由体积理论)、合成过程和选用准则,并对聚酯增塑剂进行分类,包括生物基聚酯增塑剂、石油基聚酯增塑剂。
