<p>PROBLEM TO BE SOLVED: To eliminate the necessity of a heat-treatment for a post- crystallization, and manufacture a container which has less deformation and is excellent in heat-resistance and chemical-resistance by using a resin composition containing a thermoplastic crystalline polyimide resin having a specified repeating structure, which totally crystallizes in an injection-molding die. SOLUTION: By using a resin composition wherein a weight ratio between a crystalline polyimide resin A having a repeating structural unit of a general formula I, and of which the logarithmic viscosity (ηinh) is in a range of 0.1-3.0 dl/g, and a crystalline polyimide resin B having a repeating structural unit of a general formula II, and of which the logarithmic viscosity (ηinh) is in a range of 0.1-3.0 dl/g, is in a range of 10/90-99.9-0.1, this heat-resistant holding container is manufactured by an injection-molding or an extrusion-molding or the like. For this resin composition, by totally achieving the crystalization in a die, the original heat-resistance and chemical-resistance of the polyimide resin are displayed, and at the same time, a heat-resistance container without a dimensional change by a heat-treatment for a post-crystallization, can be manufactured.</p> |
