PROBLEM TO BE SOLVED: To obtain a pest-repellent-containing composition for injection molding which can be efficiently and smoothly injection molded, is excellent in bleeding properties of a pest repellent while securing excellent impact resistance of polypropylene after molding, and exhibits good slow effectiveness over a long period; and to provide an injection molded article using the composition. SOLUTION: The composition for injection molding is prepared by incorporating the pest repellent into a polypropylene resin as a carrier. The polypropylene resin is a random copolymer, and the pest repellent comprises an alkylalkanolamine which is liquid at normal temperature. COPYRIGHT: (C)2005,JPO&NCIPI |
