<p>8CH-2308 Reinforced, impact modified thermoplastic polyester compositions are provided which comprise a poly(1,4-butylene terephthalate) resin, a poly(ethylene terephthalate) resin, a fibrous glass reinforcement f filler and, as an impact modifier therefor, a polyolefin or olefin based copolymer resin. The polyolefinic impact modifier is easily dispersed in the compositions and provides significantly improved impact strength in surprisingly small amounts, in comparison with corresponding compositions which are unmodified.</p> |
