    摘要： A process for the continuous processing of vinyl polymer latices to produce thermoplastically processible vinyl polymer powder by coagulating a stream of a vinyl polymer latex by the addition of a stream of a coagulant with intensive mixing and shearing in a cascade of vessels at an average residence time per vessel of 10 to 60 minutes and at temperatures from 50 to 120.degree. C., volatile auxiliary substances and residual monomers in the polymer being optionally removed by steam distillation and part of the serum separated from the vinyl polymer being added to the stream of coagulant.

    摘要： A thermoplastic molding composition that features constancy of properties, especially toughness and processability is disclosed. The composition contains a first graft rubber polymer that is a product of emulsion polymerisation of styrene and acrylonitrile in the presence of a butadiene polymer latex (A) with a mean particle diameter d50 of 80 to 220 nm, a second graft rubber polymer obtained by emulsion polymerisation of styrene and acrylonitrile in the presence of a butadiene polymer latex (B) with a mean particle diameter d50 of 340 to 480 nm, and a rubber-free copolymer of styrene and acrylonitrile. Importantly, the butadiene polymer latex (A) is the product of seed polymerization using a seed latex with a mean particle diameter of 10 to 100 nm, and the butadiene polymer latex (B) is the product of seed polymerisation using the butadiene polymer latex (A) as seed latex.
