Abstract

A polymer blend including a polyester and another thermoplastic polymer. The polyester includes terephthaloyl moieties and, optionally, other aromatic diacid moieties; and ethylene glycol moieties; optionally diethylene glycol moieties; isosorbide moieties; and, optionally one or more other diol moieties. The polyester has an inherent viscosity of at least about 0.35 dL/g.
