Thermoplastic polyester composition

Abstract

Abstract PURPOSE:To provide the titled compsn. producing molding products with excellent mechanical and thermal properties, anisotropy and appearance, prepared by adding a copolymer of alpha-olefin and alpha,beta-unsatd. acid glycidyl ester, to a specified copolyester. CONSTITUTION:The compsn. is prepared by adding 0.5-30pts.wt. olefinic copolymer consisting of alpha-olefin and alpha,beta-unsatd. acid glycidyl ester to 100pts.wt. copolyester consisting of 20-50mol% polyethylene terephalate unit and/or polyethylene isophtalate unit and 80-50mol% polyethylene 4,4'-diphenyldicarboxylate unit. When the amount of the olefinic copolymer is less than 0.5pts.wt., molding products with sufficient impact resistance and anisotropy and unobtainable and when it exceeds 30pts.wt., elastic modulus and thermal deformation point of the molding are lowered.
