    摘要: The invention relates to thermoplastic interpolymers having a certain chemical composition and to their use in thermoplastic molding compounds of polyamides and styrene copolymers and/or graft polymers for the production of improved blends of polyamides and styrene copolymers and/or graft polymers, particularly ABS polymers, having homogeneous surfaces and improved mechanical properties. The interpolymers themselves are produced by compounding of polyamides and copolymers based on styrenes and/or acrylonitrile and/or (meth)acrylates with primary or secondary alcohols and at least one ester of (meth)acrylic acid with a tertiary C.sub.4-10 alcohol in the melt. The interpolymers act as compatibility promoters in the blends and lead to a surprising improvement in a number of properties of thermoplastic molding compounds.

    摘要: Particulate, multiphase polymers which have a core (A) and an overlying shell (B) wherein the core (A) is an organic, resinous polymer comprising polymerized olefinically unsaturated monomer units having softening point temperatures of at least 30.degree. C. and wherein the shell (B) is an organopolysiloxane are obtained by producing in a first stage an organic resinous polymer in latex form by emulsion polymerization and, in a second stage, the latex particles of the first stage are surrounded with a shell (B) organopolysiloxane by polymerizing low molecular weight organosiloxanes in the presence of the latex particles of the first stage.
