摘要:
A polyamide resin composition is produced by melt kneading (A) 20 to 60 parts of a polyamide resin and (B) 40 to 80 parts of an ethylene copolymer comprising (a) 40 to 90 wt% of an ethylene unit, (b) 5 to 60 wt% of an α,β-unsaturated carboxylic acid alkyl ester unit and (c) 0.3 to 10 wt% of a maleic anhydride unit to form a partially crosslinked composition (I) and adding 50 to 1,000 parts by weight of a polyamide resin to 100 parts by weight of the composition (I) and melt kneading the resulting mixture.
The resultant composition is moldable and has excellent impact resistance.
Preferably to the composition (I) is added a polyfunctional compound which reacts with (B) and (C) and causes cross-linking thereof in the kneading.
