Polyester composition containing ester of polyfunctional high molecular weight alcohol

Abstract

The present invention is a composition comprising a linear saturated polyester and from 0.5 to 30 percent by weight of the polyester of at least one ester of a polyfunctional alcohol having a molecular weight of from 900 to about 1,500. The ester is of an alcohol and a carboxylic acid wherein the alcohol has the formula R.sup.1 [(OR.sup.2).sub.n OH].sub.m wherein R.sup.1 is a hydrocarbon radical of from 3 to 10 carbon atoms, R.sup.2 is a hydrocarbon radical of from 2 to 4 carbon atoms, n can be the same or a different interger of from 2 to 15, m is an integer of from 3 to 6. The alcohol has greater than 20 carbon atoms. The acid is a carboxylic acid of from 1 to 25 and preferably 3 to 10 carbon atoms, and from 1 to 10 carboxyl groups. Preferably the acid has from 3 to 10 carbon atoms and one carboxyl group.
