    • Disclosed is a polyamide resin composition for portable electronic devices, which is excellent in mechanical strength, thin shape formability, crystallinity and warping property. Specifically disclosed is a polyamide resin composition containing 30-80% by weight of a polyamide MP (A) and 20-70% by weight of a polyamide resin (B) having a melting point not less than 245°C (with the total amount of them being 100% by weight). The polyamide resin composition further contains, as a filler (C), a fibrous filler (C1) as an optional component and a plate-like filler (C2) as an essential component, and the content ratio (C1):(C2) is from 0:10 to 9:1. The total amount of the filler (C) is 30-250 parts by weight relative to 100 parts by weight of the total of the polyamide MP (A) and the polyamide resin (B). The polyamide MP (A) is a polyamide resin obtained by a polycondensation reaction between a mixed diamine, which contains 90-50% by mole of meta-xylylenediamine and 10-50% by mole of para-xylylenediamine, and an E,i-linear aliphatic dibasic acid and/or an aromatic dibasic acid.
    • 公开了一种便携式电子器件的聚酰胺树脂组合物,其机械强度,薄形状成形性,结晶度和翘曲性优异。 具体公开了一种聚酰胺树脂组合物,其含有30-80重量%的聚酰胺MP(A)和20-70重量%的熔点不低于245℃的聚酰胺树脂(B)(总量 其中100重量%)。 作为填料(C),聚酰胺树脂组合物还含有作为必要成分的作为任意成分的纤维状填料(C1)和作为必要成分的板状填料(C2),含量比(C1):(C2)为 从0:10到9:1。 相对于100重量份聚酰胺MP(A)和聚酰胺树脂(B)的总量,填料(C)的总量为30-250重量份。 聚酰胺MP(A)是通过含有90-50摩尔%间苯二甲胺和10-50摩尔%对苯二甲胺的混合二胺与E,i- 直链脂族二元酸和/或芳族二元酸。
