ACRYLIC RUBBER LATEX, ITS MANUFACTURING METHOD, COMPOSITE RUBBER GRAFT COPOLYMER, AND THERMOPLASTIC RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an acrylic rubber latex which has a specific composition and has a small particle size distribution; to provide a manufacturing method of an acrylic rubber latex which is suitably used for suppressing the generation of a polymer scale during polymerization; to provide a compound rubber graft copolymer which is capable of forming a molding with excellent moldability, impact resistance and weatherability; and to provide a thermoplastic resin composition. SOLUTION: The acrylic rubber latex is characterized by containing particles of an acrylic rubber (A) comprising 50 mass% or more of a 2-ethylhexyl acrylate unit and having a ratio (dw/dn) of a mass average particle size (dw) and a number average particle size (dn) of 1.0-1.3. The manufacturing method of the same is also provided. The compound rubber graft copolymer using the acrylic rubber and the thermoplastic resin composition are also provided.
