PURPOSE:To obtain the subject composition having excellent strength, flexibility, heat resistance and oil resistance, comprising a polyester composed of an aliphatic dicarboxylic acid, an aliphatic diol and a monoalcohol, a polyamide and a polycarbodiimide. CONSTITUTION:(A) 10-90 pts.wt. polyester composed of an aliphatic dicarboxylic acid of formula I (n is 0-10), an aliphatic diol and one or more hydroxy compounds of a dihydroxy compound of formula II (R<1> and R'' are alkylene; is 3 or 4; q and r are 0 or >=1) and a monohydroxy compound of formula III (R<3> is alkylene; (l is 2 or 3; m is 0 or >=1), having 2-10mol% content of the compounds of formula II and formula III based on the whole monomer constituting the component A and 0.8-2.0 intrinsic viscosity in o-chlorophenol at 30 deg.C is blended with (B) 90-10 pts.wt. polyamide having 1.8-4.0 intrinsic viscosity in 1g/dl concentration in 98% sulfuric acid at 20 deg.C and 0.1-5.0 pts.wt. polycarbodiimide based on 100 pts.wt. total amounts of the components A and B to give a resin composition. |
