PURPOSE:The titled composition, obtained by blending a graft polymer prepared from a crosslinked acrylic rubber, etc., of a multiple structure having a core of a rigid crosslinked resin in particles of an acrylic acid ester based rubber with AES resin, etc., in specific amounts and having improved weather, impact resistance, molding external appearance, etc. CONSTITUTION:A composition obtained by blending (A) 5-95wt% graft polymer prepared by polymerizing (A2) a monomer mixture consisting of 10-90wt% one or more aromatic vinyl compounds, e.g. styrene, etc., and 90-10wt% one or more ethylenically unsaturated monomers expressed by the formula CH2=CRX (R is H, etc.; X is CN, etc.), e.g. acrylonitrile, etc., in the presence of (A1) a latex containing a crosslinked acrylic rubber of a multiple structure containing 5-50wt% rigid crosslinked resin having 0.15-0.4mu core particle diameter in the particles and outer layer part thereof consisting of 95-50wt% crosslinked acrylic acid ester based polymer with (B) 5-95wt% AES resin and (C) 0-50wt% rigid thermoplastic resin to give 100wt% total thereof.
