<p>A method for making an epoxyfunctional organosilicon compound is provided, comprising the step of reacting at a temperature of from about 25 DEG to about 100 DEG C a mixture comprising (A) an ethylenically unsaturated epoxide; (B) an organohydrogenpolysiloxane or organohydrogensilane; and (C) a rhodium complex catalyst selected from the group consisting of: (i) RhX3(SR2)3; (ii) RhX3 . xH2O; (iii) [RhX(norbornadiene)]2; (iv) RhX(CO)(R3P)3; (v) RhX(R3P)3; and (vi) [RhCl(cyclooctadiene)]2; wherein X is a halogen atom, x is a number equal to 3 or 4, and R is an alkyl radical having from 1 to 8 inclusive carbon atoms, aryl, aralkyl, or alkaryl radical or the R1_3SiQ- group in which Q represents a divalent aliphatic hydrocarbon radical having from 1 to 6 inclusive carbon atoms and R<1> represents an alkyl radical having from 1 to 8 inclusive carbon atoms, aryl, aralkyl, or alkaryl radical or a (CH3)3Si- radical. v</p> |
