| 摘要 |
The invention deals with a polysiloxane dispersion with a 25 to 00.0% by weight outer phase consisting of monomeric or polymeric polyoles liquefying at temperatures of 20 to 100.degree.C, linear or ramified polyglycolethers, polyesters on a polyole base, and aliphatic, cycloaliphatic or aromatic dicarboxylic acids, aliphatic polylactones and/or polycarbonates, 0.1 to 75% by weight of a dispersed phase consisting of one or several three-dimensionally polymerizable polyorganosiloxanes, the polymerized polyorganosiloxane particles having a mean diameter of 0.02 to 50 .mu.m, and 0 to 20% by weight solvents, softeners, polymerizers, catalysts, stabilizers, dispersants, hardeners, reaction-mediators, and/or agents to influence the viscosity of the outer phase. The invention further deals with a process for the production of these polysiloxane dispersions and their use as preliminary products for the production of silicon-modified thermoplastic, duroplastic or elastomeric plastics on a polyurethane, polyurea, saturated polyester and polycarbonate base.
