Abstract
Impact-modified and moldability-improved polyethylene terephthalate molding compositions are provided which comprise polyethylene terephthalate resins, a copolymer of .alpha.-olefins and glycidyl esters of .alpha.,.beta.-ethylenically-unsaturated carboxylic acids and barium salt of fatty acids. Glass fiber reinforcement of the polyester compositions is preferable because of further enhancement of the moldability of the polyester composition thereof. In addition, resistance to moist heat is also increased.
