    摘要： Particulate, multiphase polymers which have a core (A) and an overlying shell (B) wherein the core (A) is an organic, rubber-like polymer comprising polymerized olefinically unsaturated monomer units having softening point temperatures below 0.degree. C. and wherein the shell (B) is an organopolysiloxane are obtained by producing in a first stage an organic rubber-like 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) or organopolysiloxane by polymerizing low molecular weight organosiloxanes in the presence of the latex particles of the first stage.
