Abstract: PURPOSE:To obtain a resin compsn. having excellent moldability and physical properties, by injection-molding a compsn. consisting of a polyamide resin mainly composed of a xylyleneadipamide unit and a polyester resin mainly composed of a butylene terephthalate unit. CONSTITUTION:A compsn. consisting of 98-50wt% polyamide resin (A) mainly composed of a xylyleneadipamide as a main structural unit and 2-50wt% polyester resin (B) mainly composed of a butylene terephthalate unit as a main structural unit is injection-molded by using a mold at 100 deg.C or below. Examples of the polyamide resins are m-xylyleneadipamide alone and xylyleneadipamide mixtures of at least 60wt% m-xylyleneadipamide and at most 40wt% p- xylyleneadipamide. When injection molding is carried out at a mold temp. of 100 deg.C or below, a molding having excellent physical properties can be obtd. with good moldability. The mold temp. of exceeding 100 deg.C gives no increased benefits in respect of energy and cost.

Abstract: PURPOSE:A resin composition excellent in impact resistance, heat resistance, flexibility, moldability, etc., comprising a polyamide resin and a modified polyolefin having a specified functional group. CONSTITUTION:A resin composition comprising 5-98wt% polyamide resin (e.g., nylon 6 or 66) and a modified polyolefin containing 0.001-10mol% at least one functional group selected from among those of formulas I , II, and III (wherein R1-R5 are each H or an organic group), e.g., ethylene/proplylene compolymer having 0.18mol% functional groups of formula IV in side chains. Because the above functional groups contain imido, amido, or like groups and are similar in structure to units constituting a polyamide, this modified polyolefin shows good compatibility with a polyamide. Therefore, it is possible to obtain a resin composition having well-balanced excellent impact resistance, heat resistance, flexibility, fluidity etc.
