POLYESTER COMPOSITIONS CONTAINING AN IMPACT MODIFIER

摘要

Disclosed are novel polyester compositions comprising (i) at least one polyester containing diol residues comprising ethylene glycol residues and diacid residues comprising terephthalic acid residues, 2,6-naphthalene-dicarboxylic acid residues or a mixture thereof, and containing antimony metal; (ii) certain epoxy-containing impact modifiers; and (iii) a phosphorus compound. The polyester compositions exhibit improved toughness and are useful in the manufacture or shaped articles by injection molding and in extruding film and sheet material.
