Abstract: Preparation of a thermoplastic molding composition, comprises agglomerating a rubber latex using an agglomerating agent comprising a dispersion of polymer made from 80-100 wt.% 1-12C alkyl acrylates and 0-20 wt.% comonomers forming water-soluble polymers. The agglomerating agent is prepared by polymerizing the acrylate polymer dispersion in the presence of molecular weight regulator. Preparation of a thermoplastic molding compositions, comprises (a) polymerizing dienes and/or 1-12C alkyl acrylates, in aqueous emulsion, to give a rubber latex with a glass transition temperature of -10 degrees C. About 0-30 wt.% of the acrylate monomers may be replaced by other copolymerizable monomers, and 0-10 wt.% of the acrylate monomers may be replaced by crosslinking monomers; (b) agglomerating the latex by adding an agglomerating agent comprising a dispersion of a polymer from 80-100 wt.% 1-12C alkyl acrylates and 0-20 wt.% comonomers forming water-soluble polymers. 0-50 wt.% of these monomers may be replaced by other copolymerizable polymers; and (c) polymerizing in an aqueous emulsion (i) 10-90 parts by weight styrene, alpha -methylstyrene, (meth)acrylonitrile, 1-12C alkyl acrylate, and/or 1-6C alkyl methacrylate, where 30 wt.% may be replaced by other copolymerizable polymers; and (ii) 10-90 wt.% of the agglomerated latex to give a graft polymer. The agglomerating agent is prepared by polymerizing the acrylate polymer dispersion in the presence of molecular weight regulator (0.001-10 wt.%, based on the amount of polymer dispersion). An Independent claim is also included for a fiber, film, or a molding made from the obtained molding composition.
