  • Telomerisation of cyclic polyorganosiloxanes
    Patent number: 10047198
    Abstract: A telomerization process is used to prepare a reaction product containing a noncyclic hydrocarbonoxy-functional polyorganosiloxane. The process includes heating a composition including (A) a cyclic polyorganosiloxane, (B) a silane, and (C) a Lewis Acid telomerization catalyst. The cyclic polyorganosiloxane has formula [(R12SiO)2/2]n, where subscript n is an integer of 4 or more, and each R1 is independently H, a hydrocarbyl group, or a halogenated hydrocarbyl group. The silane has formula R2(4-m)Si(OR3)m, where subscript m is an integer from 1 to 4, each R2 is independently H, a hydrocarbyl group, or a halogenated hydrocarbyl group, and each R3 is independently a hydrocarbyl group.
