Abstract
A chelated titanium catalyst can be improved by the addition of an additive selected from the group consisting of organomercaptan of the formula RSH, where R is a hydrocarbon radical containing from 3 to 12 carbon atoms, and mercapto containing silane of the formula HSR'SiX.sub.3, where R' is a divalent hydrocarbon having from 1 to 8 carbon atoms and X is alkoxy radical having 1 to 6 carbon atoms. The improved composition has a reduced tendency to develop color upon storage. The improved composition is particularly useful in a silicone composition comprising a hydroxyl endblocked polydiorganosiloxane and an alkoxysilane or mixture of alkoxysilanes, or in a silicone composition comprising an alkoxy endblocked polydiorganosiloxane.
