Abstract
Diesters of 1,4-cyclohexane dicarboxylate are surprisingly more efficient PVC plasticizers and fuse PVC faster and at a lower temperature than similar phthalates or terephthalate diesters. Hydrogenated orthophthalate diesters are slower fusing, i.e., require higher temperatures, than do the corresponding orthophthalate diesters.
