Реферат: Process for obtaining impact-resistant thermoplastic molding compositions based on polymers in the form of rubber with a vitrification temperature of less than -20º c, comprising the following steps A) polymerization of butadiene, of an acryl ester, their mixtures with one another or with up to 30% by weight of other monomers, in aqueous emulsion to a rubber latex with an average particle size (d50 value of the mass distribution) integral) less than 0.15 μ m, B) agglomerating the rubber latex and increasing the size of a part of the rubber particles so that the rubber latex has an average particle size of 0.16 to 0.45 μm (d50 value of the distribution of integral masses). C) polymerization of 20 to 90 parts by weight of styrene, acrylonitrile, methyl methacrylate or mixtures thereof, in aqueous emulsion, in the presence of 80 to 10 parts by weight of the agglomerated rubber latex, based on the solids and, in case dice, D) mixing from 10 to 60% by weight of this graft polymer with 90 to 40% by weight of a hard polymer of styrene, α-methylstyrene, methylmethacrylate, acrylonitrile, methacrylonitrile, vinyl chloride or mixtures of these monomers, Characterized in that the agglomeration is carried out at 20-90ºC by addition of an agglomeration agent based on a dispersion of acrylic ester polymer to the rubber latex.
