Abstract
Plasticizers are made from oil with a narrowed, fatty acid polydispersity and extracted from a microorganism, such as a natural or genetically modified bacterium or algae. These plasticizers can comprise either a large content of either saturated C4 and/or C6 triglycerides or unsaturated C12 or greater triglycerides that have been chemically modified by one or more of epoxidation, acylation and esterification. The plasticizers of this invention are particularly well-suited for use with polar polymeric resins such as PVC.
