Abstract
Disclosed are compositions comprising blends of (a) a polyester having an inherent viscosity of about 0.4-1.5, (b) about 5 to about 35 weight %, based on the weight of the composition, of polyethylene having a melt index of about 0.1-15.0 and a density of about 0.910-0.965, and (c) about 0.25 to about 5 weight %, based on the weight of the composition, of poly(tetramethylene terephthalate)-co-2-butene-1,4-diol having an inherent viscosity of 0.9 to 1.5 grafted with a low density polyethylene. These compositions are especially useful as molding compositions because of their high impact strength.
