Polyester plasticizer having high cold resistance and polyvinyl chloride composition including the same

Abstract

A polyester plasticizer having high cold resistance and a polyvinyl chloride composition including the same. The polyester plasticizer can be obtained by an esterification reaction of a diacid component with a diol component followed by end-capping with an end-capping agent. The diacid component is sebacic acid. The diol component includes a first diol and a second diol. The first diol is diethylene glycol, and the second diol is a diol having a silicon-oxygen structural unit, a linear chain structure, or a branched chain structure. Therefore, the polyester plasticizer can be used in a polyvinyl chloride composition, so as to improve low-temperature resistance, bendability, and plasticizer blooming resistances of a resulting PVC soft product.
