PHTHALATE-FREE, EPOXIDIZED PLASTICIZER COMPOSITIONS COMPRISING FATTY ACID ESTERS AND BIO-BASED OILS, AND METHODS OF MAKING THE SAME

摘要

There is disclosed a phthalate-free, epoxidized plasticizer composition comprising a blend of: a) one or more fatty acid esters having less than 10% saturates; and b) one or more bio-based oil having an oxirane value of at least 5.0 %. There is also disclosed a method of making a phthalate-free, epoxidized plasticizer composition comprising forming a blend of the fatty acid esters bio-based oils, wherein the one or more fatty acid esters and the bio-based oils are epoxidized either prior to forming the blend or in a single epoxidation step after the blend is formed. Plasticized composition containing the phthalate-free, epoxidized plasticizer composition, as well as articles made from such compositions are also disclosed.
