Description

ABSTRACT:
The invention provides a process for producing epoxy-functional silicones by a rhodium metal complex-catalyzed hydrosilation reaction between an SiH-containing silane or siloxane and an olefin epoxide, in the presence of a tertiary amine stabilizer. In practicing the invention, RhCl.sub.3 [(CH.sub.3 (CH.sub.2).sub.3).sub.2 S].sub.3 or PtCl.sub.2 [(CH.sub.3 CH.sub.2).sub.2 S].sub.2 are suitable hydrosilation catalysts and methyldicocoamine, CH.sub.3 (C.sub.18 H.sub.37).sub.2 N, is a suitable stabilizer. The invention also provides for a composition including an SiH-functional silane or siloxane, and a tertiary amine, where the composition is not susceptible to gelation during a hydrosilation addition reaction. The invention further provides a method for stabilizing epoxysilicones both during and after the hydrosilation addition reaction used in their production.
