INCORPORATING AN ASYMMETRICAL SILOXANE INTO A COMPOSITION IN NEED OF HYDROLYSIS RESISTANCE |
摘要 |
An asymmetric siloxane is made by reacting a silicone having the formula MHDxM′H where MH is R1R2HSiO1/2, M′H is R4R5HSiO1/2 and x is an integer 0≰x≰10 under selective hydrosilylation conditions in the presence of a precious metal hydrosilylation catalyst, with a first olefinic compound and in a second step, a monohydridosiloxane produced in the first step is reacted under hydrosilylating conditions with another olefinic compound different from the first olefinic compound.
