摘要: A method for particles agglomeration and enlargement of a diene type polymer rubber latex, which comprises subjecting a diene type polymer rubber latex produced by emulsion polymerization, to particles agglomeration and enlargement to obtain a particles-enlarged diene type polymer rubber latex (A), wherein the particles enlargement is allowed to take place by agglomeration based mainly on Brownian coagulation; a graft copolymer (B) of a particles-enlarged diene type polymer rubber latex (A) obtained by the above method; and a thermoplastic resin composition comprising said graft copolymer (B).

摘要: A resin composition comprises (A) a polycarbonate resin, (B) a saturated polyester resin and/or polyester-based elastomer, and (C) a copolymer obtained by graft-polymerizing a given monomer in the presence of latex containing a butadiene-based rubber polymer. The graft copolymer is obtained under the following conditions (a) to (c): (a) the polymerization formulation is composed of 60 to 90% by weight of the butadiene-based rubber polymer and 10 to 40% by weight of the monomer, (b) the monomer formulation of the latex is composed of 50 to 100% by weight of butadiene and 0 to 50% by weight of vinyl-based monomers copolymerized with butadiene, and (c) the latex has a weight-average particle size from 100 to 200 nm, and the ratio dw/dn of the weight-average particle size to the number-average particle size is 1 or more and 3 or less. According to the present invention, a thermoplastic resin composition excellent in production stability and having excellent impact resistance and molded appearance is provided.
