example 1
A total of 100 parts by weight of a polyamide elastomer (produced by Daicel-Huels Ltd., under the trade name of "Daiamide PAE") 0.5 part by weight of an antioxidant (produced by Ciba Specialty Chemicals Corporation, under the trade name of "Irganox 245"), and 2 parts by weight of polypropylene glycol (a reagent produced by Nacalai Tesque, Inc.) were compounded using a biaxial extruder, and the resulting compound was injected and molded at a temperature of 280.degree. C. using an injection molding machine to thereby yield test pieces [a tensile dumbbell (according to ASTM D 638), flexural dumbbell (according to ASTM D 790), and IZOD impact test dumbbell (with notches) (according to ASTM D 256) each according to ASTM specifications].
