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 thereofC2: an ether compoundC3: a tetrahydroaromatic compoundC4: a cyclopentane compoundD1: carbonyl groupD2: cyclic iminoether groupD3: epoxy groupD4: hydroxyl groupD5: amino groupD6: nitrile group
