アミド化合物の結晶を微細化する方法を含むポリプロピレン系樹脂成形体の製造方法、該製造方法により得られるポリプロピレン系樹脂成形体、及びその二次加工成形品

摘要

PROBLEM TO BE SOLVED: To provide: a method for refining a crystal in a process that manufactures a polypropylene-based resin composition in a system that contains a needle crystal of an amide compound existing in a polypropylene-based resin; a method of manufacturing the polypropylene resin shaped article including the method; the polypropylene resin shaped article obtained by the manufacturing method; and a secondary processing molding of the same.SOLUTION: A method of manufacturing a polypropylene resin shaped article is characterized by adjusting a diameter of a strand at cooling solidification to a range from 0.5 mm to 2.0 mm in a process to cool a molten polypropylene-based resin composition to deposit a needle crystal of an amide compound.
