Composition for injection molding.

摘要

A composition for injection molding well-balanced in rigidity, impact resistance, appearance of molded products and moldability is obtained by using as an essential component a partially crosslinked product being prepared by dynamically heat-treating: (A) 40-100% by weight of an alpha -olefin (co)polymer resin having 2 to 8 carbon atoms; (B) 0-60% by weight of rubbery substance; 0.01-0.07 parts by weight, based on 100 parts by weight of said components (A)+(B), of at least one crosslinking agent selected from: (C) a dihydroaromatic compound or a polymer thereof, (D) an ether compound, (E) a tetrahydroaromatic compound, and (F) a cyclopentane compound; and (G) 0.01-7 parts by weight of a polyfunctional monomer based on 100 parts by weight of said components (A)+(B). a
