Graft-modified substance, process for preparing same, and thermoplastic resin composition using the graft-modified substance.

摘要

A modified thermoplastic resin composition superior in adhesive property and mechanical strength is obtained by treating a thermoplastic resin (A) and/or a rubbery substance (B) with at least one kind of a monomer (D) containing at least one functional group selected from the following (D1) to (D6) in the presence of at least one compound as a modifying agent (C) selected from the following (C1) to (C4): C1: a dihydroaromatic compound or a polymer thereof C2: an ether compound C3: a tetrahydroaromatic compound C4: a cyclopentane compound D1: carbonyl group D2: cyclic iminoether group D3: epoxy group D4: hydroxyl group D5: amino group D6: nitrile group s
