대표청구항 ▼

A polyester molding composition comprising (A) 60-97 weight % based on the total of components A and B of a polyester matrix resin having an inherent viscosity of at least 0.3, wherein the polyester consists essentially of a linear saturated condensation product of at least one glycol selected from the group consisting of neopentyl glycol, cyclohexane dimethanol and aliphatic glycols of the formula HO(CH2)nOH where n is an integer of 2 to 10 and at least one aromatic dicarboxylic acid having 8 to 14 carbon atoms, or reactive derivatives thereof, and (B) 3-40 weight % based on the total of components A and B of an ethylene copolymer of the formula E/X/Y where E is the radical formed from ethylene and comprises 40-90 weight percent of the ethylene copolymer, X is the radical formed from [Figure] where R1 is alkyl of 2-8 carbon atoms and R2 is H, CH3 or C2H5, and X comprises 10-40 weight percent of the ethylene copolymer, and Y is selected from the group consisting of glycidyl methacrylate and glycidyl acrylate, and Y comprises 0.5-20 weight percent of the ethylene copolymer. The compositions of claim 1 which also contain 0-15 parts by weight of plasticizer per hundred parts of the matrix resin. The compositions of claim 15 where the plasticizer is a compound of the formula [Figure] where m is an integer from 1 to 3, inclusive, n is an integer from 4 to 25, inclusive, X is CH3, C2H5 or H, A is alkyl, acyl or aroyl of 1-10 carbon atoms, and B is alkyl, acyl or aroyl of 1-10 carbon atoms.
