摘要：
The resin composition of the present invention allows the molding of a hollow molded product, able to stably form a long parison and having a three-dimensionally curved shape, by the formation of a copolyamide having a melting point of 225.degree. C. or more and a crystallization temperature of 230.degree. C. or less obtained by a polymerization of 66, 6T and 6I components at a specific compounding ratio.
