摘要： A polyester resin composition for forming an impact resistant article is described, comprising from 40 to 97 parts by weight of polyethylene terephthalate and from 3 to 60 parts by weight of at least one polyester selected from(1) an ethylene terephthalate-based polyester comprising from 5 to 25 wt % of at least one dibasic acid represented by formula (I) ##STR1## wherein A and B each represents a hydrogen atom, an alkyl group, or a phenyl group, and n is an integer of not less than 10, and ester bond-forming derivatives,(2) an ethylene terephthalate-based polyester comprising 3 to 25 wt % of at least one polyalkylene glycol having a molecular weight of from about 500 to 20,000, and(3) polyarylate, which composition further contains, per 100 parts by weight of the polyester, (a) from 0.05 to 10 parts by weight of at least one of an inorganic crystal nucleating agent having an average particle diameter of not more than 50 .mu.m, an organic compound containing a metal salt of a carboxyl group, and a polymer compound containing a metal salt of a carboxyl group, (b) from 3 to 30 parts by weight of modified polyolefin or modified olefin-based elastomer prepared by adding from 0.001 to 10 mol % of an alicyclic carboxylic acid containing a cis-double bond in the ring or its functional derivative to a polyolefin or olefin-based elastomer, (c) from 1 to 30 parts by weight of a copolymer comprising from 80 to 99 wt % of .alpha.-olefin, from 1 to 20 wt % of glycidyl methacrylate or glycidyl acrylate, and up to 19 wt % of vinyl acetate, (d) from 0.3 to 10 parts by weight of an ester-based plasticizer, and (e) up to 150 parts by weight of a fibrous reinforcing material.
