<p>Composition comprising a linear saturated polyester and from 0.5 to 30 percent by weight of the polyester of at least one ester of an ethoxylated polyfunctional alcohol having a molecular weight of from 500 to about 1,500. The ester is of an ethoxylated aromatic alcohol and a carboxylic acid wherein the ethoxylated aromatic alcohol has the formula, HO (RO)n - R1 - (OR)¿n? - OH; wherein R is the same of different hydrocarbon radical of from 2 to 4 carbon atoms, n can be the same or a different integer of from 2 to 15; and R?1¿ is an aromatic radical preferably derived from an aromatic dialcohol, most preferably bisphenol A. The ethoxylated aromatic 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.</p> |
