PURPOSE:To produce a polyamide blow molding especially a three-dimensional blow molding excellent in heat resistance, residence stability in a molten state and impact resistance by mixing a specified polyamide with a specified resin and a heat resistance improver to form an intimate mixture improved in residence characteristics in a molten state. CONSTITUTION:A polyamide blow molding made from a mixture of 100 pts.wt. intimate mixture comprising 50-95wt.% crystalline polyamide (A) comprising 50-90wt.% hexamethyleneadipamide component, 5-40wt.% hexamethyleneterephthalamide component and 5-30wt.% hexamethyleneisophthalamide component and satisfying the relationships: melting temperature (Tm)>=225 deg.C and crystallization temperature (Tc)<=230 deg.C and 5-50wt.% ethylene ionomer resin and/or carboxy-modified elastomer (B) and having a melt viscosity satisfying formulas I and II and 0.001-10 pts.wt. heat resistance improver (C), wherein the mean particle diameter of the dispersed phase comprising component B dispersed in the polyamide matrix phase is 10mum or below. |
