MODIFICATION METHOD OF POLYPROPYLENE RESIN MOLDED BODY, MODIFIED POLYPROPYLENE RESIN MOLDED BODY, AND MANUFACTURING METHOD THEREFOR

摘要

To provide a method for modifying a polypropylene resin molded body by a side chain crystalline block copolymer having a long chain alkane chain in a side chain, good interaction force with a polypropylene resin molded body, and function capable of modifying a surface property, and a modified polypropylene resin molded body.SOLUTION: There is provided a modification method of a polypropylene resin molded body having a process for contacting a copolymer solution containing a side chain crystalline block copolymer and a polypropylene resin molded body at a temperature of the copolymer solution of 40 to 120°C. There is provided a modified polypropylene resin molded body having a substrate of the polypropylene resin molded body and a part containing the side chain crystalline block copolymer in at least a part of the substrate.SELECTED DRAWING: Figure 1
