MANUFACTURING METHOD OF GRANULATED BODY OF POLYPROPYLENE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a granulated body of a polypropylene resin composition having high intrinsic viscosity and suppressed generation of fish eye even with having a propylene ethylene random copolymer with high percentage of content.SOLUTION: There is provided a manufacturing method of a granulated body of a polypropylene resin composition of the like including granulation of a polypropylene resin composition (C) containing at least two kind of a propylene (co)polymer (A) having MFR of 0.5 to 100 g/10 min. and a propylene ethylene random copolymer (B) having intrinsic viscosity of 6 to 20 dl/g by using a metal filter (D) knitted by a longitudinal wire and a lateral wire as shown in Figure 1, where the longitudinal wire is lined with a predetermined distance interval and the lateral wire satisfies requirements such as having a structure with a phase contact with neighboring lateral wire.SELECTED DRAWING: Figure 1
