    摘要: A semiaromatic polyamide resin composition of the present invention contains a polyamide (A) in which a dicarboxylic acid component unit comprises a terephthalic acid component unit and a diamine component unit comprises a straight-chain alkylenediamine component unit and an alkylenediamine component unit having a side-chain alkyl group; and a modified ethylene/.alpha.-olefin copolymer (B) obtained by graft-modifying an ethylene/.alpha.-olefin copolymer having particular properties with an unsaturated carboxylic acid or a derivative thereof. A molded article obtained by using this composition exhibits excellent anti-creeping property under high-temperature and high-humidity conditions, and causes the metal mold to be little fouled during the molding operation.

    摘要: A semiaromatic polyamide resin composition comprising: (A) a polyamide copolymer in which a main constituent component unit is a polyamide formed of a recurring unit of a dicarboxylic acid component unit and a diamine component unit, at least not less than 45 mol % of said dicarboxylic acid component unit being a terephthalic acid component unit, and said diamine component unit comprising a straight-chain alkylenediamine component unit and/or an alkylenediamine component unit having a side-chain alkyl group; (B) an aliphatic polyamide containing, a unit derived from a lactam having 12 carbon atoms, a unit derived from an aminocarboxylic acid having 12 carbon atoms or a unit derived from a dodecanoic diacid and a diamine; and (C) a graft-modified product of a graft-modified ethylene/&agr;-olefin copolymer, a graft-modified product of an aromatic vinyl compound/conjugated diene copolymer, or a graft-modified product of a hydrogenated product of the aromatic vinyl compound/conjugated diene copolymer. The resin composition little precipitates the oligomer during the molding, little causes the vent of the metal mold to be clogged, is suited for conducting the molding operation for extended periods of time, and further exhibits excellent resistance against aging by heat, anti-creeping property, shock resistance and ejectability.
