<p>PROBLEM TO BE SOLVED: To provide a molded body of polyolefin in which the crystal structure of a molding is uniform, and further, crystallinity is high, and a method for molding the same.SOLUTION: Provided is a method for molding a molded body in which the ratio of the crystal structure belonging to a shish structure is 1 to 30% by weight ratio and the ratio of the crystal structure belonging to a kebab structure is 30 to 90% by weight ratio. Also provided is a method for molding a molded body characterized in that polyolefin is extruded into a mold at a fixed speed in such a manner that a resin flow is made into a layer flow at a temperature more than the melting point calculated from a peak temperature measured by a differential scanning calorimetric analysis apparatus, and then held at the above temperature.</p> |
