Title:
GRAFT COPOLYMER, THERMOPLASTIC RESIN COMPOSITION, MOLDING, AND METHOD FOR PRODUCING GRAFT COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2013/008829
Kind Code:
A1
Abstract:
Provided is a thermoplastic resin composition having excellent weather resistance, impact resistance and fluidability as well as excellent color-developing properties, thermal stability in residence and the like. Provided are: a graft copolymer (A) produced by the graft polymerization of a given amount of a composite rubber (a1) comprising a conjugated diene rubbery polymer and a crosslinked acrylic acid ester polymer and a given amount of a specific monomer (a2), the graft copolymer (A) being characterized in that the tetrahydrofuran-soluble fraction in the composite rubber (a1) has a weight average molecular weight of 50000 or more in terms of polystyrene content and the degree of swelling of the composite rubber (a1) in toluene is 7.0 or more, or that, with respect to the composite rubber present in the graft copolymer, the number of particles each having an equivalent circle diameter of 150 nm or less of the composite rubber is 50% or less of the total number of particles of the composite rubber; and others.
