Abstract
The addition of poly(ethylene terephthalate) to core-shell resin impact modified, glass fiber and mica reinforced poly(1,4-butylene terephthalate) compositions provides articles molded therefrom with improved surface gloss, impact strength, flexural modulus, flexural strength and tensile strength. Heat distortion temperatures are elevated if not less than 2.6 nor more than 4 parts by weight of poly(1,4-butylene terephthalate) resin is present for each 1 part by weight of acrylic resin impact modifier.
