Abstract
Triesters containing two ether linkages were prepared by the acylation of dihydric alcohol, which were synthesized by the reaction of diethylene glycol with epichlorohydrin. Also, diesters were synthesized by the reaction of dichloride obtained from ethylene chlorohydrin and epichlorohydrin with some fatty acid salts, and they were acetylated to yield triesters. These triesters were evaluated as plasticizers for polyvinyl chloride by comparison with dioctyl phthalate (DOP) in the same manner as the previous paper. They were superior than DOP in low temperature flexibility, but inferior in compatibility.
