ABSTRACT:
This invention relates to a composition comprising a linear, saturated polyester, such as poly(ethylene terephthalate), containing between about 4% and about 10% by weight of the poly(ethylene terephthalate) of a hydrocarbon carboxylic acid and/or an organic polymer containing pendant acid carboxyl groups, where the acid groups are neutralized by a first cation selected from Group IA of the Periodic Table of Elements and a second cation selected from Groups IIIA, IIIB and IVB. The first cation is present in an amount less than 50% of the total metal ions and neutralizes not more than 20% of the hydrocarbon acid groups or carboxylic acid groups of the organic polymer. The second cation neutralizes up to 100% of the remaining hydrocarbon acid or carboxyl acid groups. Preferably, the first cation is sodium and the second cation is aluminum. The composition can contain up to about 150% filler and a suitable plasticizer.
