Plasticizers, polymer compositions and processes for making the plasticizers

摘要

A process can prepare a compound having the formula;wherein R1, R2 and R3 are independently selected from hydrogen and acyl groups,wherein at least one of R1, R2 and R3 is a branched chain long acyl group including 2, 4 or 6 branched acyl groupswherein at least one of R1, R2 and R3 is selected from short acyl groups of the formula;wherein q is from 0 to 4.

1. A process for the preparation of a plasticizer compound having the formula:wherein:
R1, R2 and R3 are independently selected from hydrogen and acyl groups; at least one of R1, R2 and R3 is a branched chain long acyl group including 2, 4 or 6 branched acyl groups; at least one of R1, R2 and R3 is selected from short acyl groups of the formula: q is from 0 to 4; and the process comprises the steps of:
(1) providing an unsaturated compound having the formula: wherein:
R1, R2 and R3 are independently selected from:
(a) hydrogen;(b) a C10-C22 unsaturated long acyl group having one, two or three carbon-carbon double bonds; and(c) short acyl groups of the formula: q is from 0 to 4;at least one of R1, R2 and R3 is an unsaturated long acyl group;(2) if at least one of R1, R2 and R3 is hydrogen, optionally acylating the compound; and(3) either step (3a) or step (3b):
(3a) both of the following:
(i) hydroxylating the C10-C22 unsaturated long acyl group, and(ii) acylating the hydroxylated long acyl group with a carboxylic acid of the formula: wherein p is from 0 to 4 to provide a branched long acyl group including 2, 4 or 6 branched acyl groups; or(3b) reacting the unsaturated long acyl group with a carboxylic acid of the formula: wherein p is from 0 to 4 to provide a branched long acyl group including 2, 4 or 6 branched acyl groups.
