MOLDED ARTICLE MADE OF POLYACETAL COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide a molded resin article having high rigidity as well as toughness while keeping the excellent properties of polyacetal resin such as appearance, sliding property and thermal stability. SOLUTION: The objective molded article composed of a polyacetal copolymer having a branched or crosslinked structure has the ratio of X-ray diffraction intensity in the flow direction of the article to the intensity in the direction perpendicular to the flow direction satisfying the general formula (1): 0.7<=Fx/Rx<=1.0... (1) (Fx is the ratio of X-ray diffraction intensity of [100] plane measured in a manner that the plane including the incidence direction and the transmitting direction of X-ray becomes the direction same as the flowing direction of the molded article to the amorphous halo intensity; and Rx is the ratio of X-ray diffraction intensity of [100] plane measured in a manner that the plane including the incidence direction and the transmission direction of X-ray becomes the direction perpendicular to the flow direction of the molded article to the amorphous halo intensity).
