GRAFT COPOLYMER AND THERMOPLASTIC RESIN COMPOSITION

摘要

A thermoplastic resin composition comprising 10 to 98 parts by mass of a graft polymer (1A) containing a rubbery polymer (1G) comprising at most 50 % by mass of diene units, 2 to 50 parts by mass of a hydroxyl-containing acrylic copolymer (1B), and 0 to 80 parts by mass of other thermoplastic resin (1F), wherein the rubbery polymer (1G) is at least one member selected from the group consisting of diene rubbers, polyorganosiloxane rubbers, and olefin rubbers; and a graft copolymer (2A) produced by grafting a vinylic polymer onto a (meth)acrylic rubbery polymer (2G) agglomerated with a latex (2K) of a copolymer bearing acid groups, wherein the (meth)acrylic rubbery polymer is one comprising two or more kinds of polyfunctional monomer units.
