Abstract
A plasticizer composition comprising vicinally diacylated fatty acid esters derived from renewable feedstocks, and a process for the preparation thereof, are disclosed. A composition comprising a halogen-containing polymer and a plasticizer composition comprising the vicinally diacylated fatty acid esters is also described. A method for plasticizing halogen-containing polymers, such as polyvinyl chloride (PVC) resins is provided. The plasticizer compositions may be added to PVC resins in amounts ranging between 1 and 200 phr.

A plasticizer composition for plasticizing halogen-containing polymers comprising at least one vicinally diacylated fatty acid ester selected from the group consisting of:
- wherein R1 and R2 are independently selected from
- m is 0, 1, 2, 3 or 4;
- R3 and R4 are independently selected from C1-C8 alkyl, phenyl, or phenyl substituted by C1-C4 alkyl;
- n is 0;
- R5 is defined as in R1;
- and
- R6 is defined as in R1.
A process for preparing vicinally diacylated fatty acid ester of general formula (I):
- wherein R1 and R2 are independently selected from
- m is 0, 1, 2, 3 or 4;
- and
- R3 is C1-C8 alkyl, phenyl, or phenyl substituted by C1-C4 alkyl;
- the process comprising the steps of:
- (i) transesterifying epoxidized monoester of fatty acid with diol to provide a composition comprising epoxidized fatty acid diester;
- (ii) acylating the epoxidized fatty acid diester or the composition containing the same with anhydride.
