A composition is disclosed comprising a polymeric component and an additive selected from the group consisting of (a) RaSi (OX)4-a, (b) a partial hydrolyzate of RaSi(OX)4-a, (c) a partial cohydrolyzate of RaSi (OX)4-a and Rb min Si (OY)4-b, and (d) a partial hydrolyzate condensation product of a siloxane and RaSi (OX)4-a wherein R, X R min , and Y are substituted or unsubstituted hydrocarbon radicals and at last one substituent per additive is an unsaturated hydrocarbon radical; and a and b have values of 0 to 3. A method of stabilizing polymers against water and electrical treeing, which comprises adding the additive as defined above, is further disclosed. |
