ABSTRACT:
Bis(bis-silylalkyl) dicarboxylates, especially maleates and fumarates, are prepared by a three-step process including esterification of malaic or fumaric acid or a functional derivative thereof with a branched dienol such as 1,6-heptadien-4-ol to form an alkadienol ester, reaction of the olefinic groups in said ester with a chlorosilane and alcoholysis of the chlorine atoms attached to silicon. The products are useful as adhesion promoters in addition curable polyorganosiloxane compositions.
