ABSTRACT:
Vinyl polymers are plasticized by incorporating therewith a composition comprising condensates having the structure: ##STR1## WHEREIN N IS FROM 2 TO 15, D is either ##STR2## A is either ##STR3## m is from 2 to 10, p in each of said condensates is 11 or 7 or admixtures thereof with the proviso that condensates wherein p is exclusively 7 are admixed with those having p equal to 11, and R and R' are either -H or -CH.sub.3, with the proviso that R and R' on adjacent carbon atoms are not the same. The preferred species is .alpha.-lauroyl-.omega.-[(propylenedioxy)lauroyl]poly[(propylenedioxy) brassyloyl], alternatively, lauric acid terminated poly[propylene brassylate]. The plasticizers are prepared by condensation polymerization, either of brassylic acid or a mixture of brassylicacid and azelaic acid, with propylene glycol in the presence of a terminator, e.g., monocarboxy- or hydroxyl-substituted alkane.
