Document Type and Number:
Japanese Patent JP2888937
Kind Code:
B2
Abstract:
A process for the preparation of mixtures of thermoplastic polymers in powder form from aqueous emulsions of a) particulate, partially crosslinked, rubber-like copolymers of a C2-C8-alkyl acrylate and/or butadiene with (based on the copolymer) up to 40% by weight of acrylonitrile, styrene or C1-C4-alkyl methacrylate, b) thermoplastic resins, and optionally c) high-rubber graft polymers of styrene, alpha -methylstyrene, acrylonitrile, methyl methacrylate and/or alkyl acrylate on a diene or alkyl acrylate rubber having a rubber content of from 50 to 95% by weight, in which aqueous emulsions of a) and b) and optionally c) having polymer contents of from 15 to 50% by weight are mixed at from 20 to 100 DEG C simultaneously, but in separate streams, continuously or semicontinuously, with a coagulate solution with coagulation of the polymers a) and b) and, if used, c), the streams are combined, and the polymer mixture is then separated off.
