Polyethylene terephthalate molding compositions

摘要

Use of a selected benzoate oligomer has been found to reduce mold deposits and to lower volatility without impairing crystallization rates of polyethylene terephthalate molding blends which contain an ionic hydrocarbon copolymer or ionic salt of a hydrocarbon acid, over polyethylene terephthalate blends which contained the ionic component and other additives.
