Abstract
Abstract A process for the preparation of an organopolysiloxane composition, comprising polymerizing at a temperature from about room temperature to 250° C. a composition by weight comprising approximately (a) 10 to 90% organopolysiloxane, (b) 4.999 to 85% of at least one of a surfactant and a water-soluble polyether, (c) 85-5% of at least one polymerizable vinyl monomer, and (d) 0.001 to 2% of a radical forming polymerization catalyst, whereby the vinyl monomer is polymerized and forms polymer bridges between (a) and (b). The resulting composition is miscible with and/or readily dispersible in water, is storage-stable and is especially useful as a textile auxiliary.
