Abstract
The invention relates to a polyamide resin composition comprising (A) nylon 4.6, (B) an aliphatic polyamide having a CH.sub.2 /NHCO ratio of from 6 to 11 and (C) a non-crystalline polyamide having a glass transition temperature of at least 100.degree. C. The composition has a decreased water absorption while retaining high mechanical strength, heat stability and chemical resistance. Dimensional stability and mechanical properties after water absorption are unexpectedly good.
