Abstract
Organopolysiloxane compositions are prepared with high throughput and less process time, by a process in which organopolysiloxanes, processing aids and fillers are mixed and kneaded in the presence of water to give raw mixtures and the raw mixtures are subsequently devolatilized and freed of water in a heating and devolatilizing step at temperatures in the range from 100° C. to 250° C.
