PURPOSE: To give a resin composition containing a polyamino-phenylene ether comprising 2 kinds of specific structural units and a polyamide resin, exhibiting excellent compatibility between both the resin components to give good component dispersion, high mechanical strength and good surface appearance of the molded products.
CONSTITUTION: This resin composition contains (A) a polyaminophenylene ether copolymer consisting of (i) structural units of formula I {(m) is 1 to 4; (n) is 0 to 3 where m+n≤4; J is formula II [(a) is 1 to 6; R1 is 1 to 20C aliphatic hydrocarbon which may be substituted with halogen atoms and whose chain may be interrupted with 0 atoms, aromatic polyvalent hydrocarbon; R2 is alkylene; R3, R4 are H, 1 to 20C alkyl], when (m) is ≥2, R3 and R4 may mutually be different; K is halogen, primary or secondary alkyl and when (n) is ≥2, each may differ from one another}, and (ii) structural units of formula III (Q is H, halogen) and having a number-average polymerization degree of 25 to 500, and (B) a polyamide resin, preferably nylon-6, preferably at a A/B weight ratio of (70 to 30)/(30 to 70).
