REINFORCED THERMOPLASTIC RESIN COMPOSITION

PURPOSE:To provide the titled compsn. having excellent resistance to heat and impact, etc., by mixing a polyamide having a specified composition with an unsaturated carboxylic acid-modified propylene polymer or modified 4- methyl-1-pentene polymer and an inorg. filler in a specified weight ratio. CONSTITUTION:90-10wt% polyamide (A) composed of an arom. dicarboxylic acid component unit mainly composed of terephthalic acid and an aliph. diamine component unit (e.g., 1,6-diaminohexane) is mixed with 10-90wt% modified propylene polymer or modified 4-methyl-1-pentene polymer (B) having a graft monomer content of 0.01-10wt%, modified by grafting an unsaturated carboxylic acid (derivative) (e.g., maleic acid) and 5-200pts.wt. (per 100pts.wt. in total of the components A and B) inorg. filler (C) (e.g., glass fiber) to obtain the titled resin compsn. The compsn. is suitable for use in the production of automobile parts, electrical components, etc.
