First Claim
1. A silicone composition, comprising:
- (a) a first silane of the formula;
##STR22## wherein;
R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 are independently selected from hydrogen, halo, and organo radicals; and
n is an integer having a value of from 1 to 4;
(b) a second silane of the formula;
##STR23## wherein;
R11 and R16 are non-polymerizable groups and are independently selected from halo and organo radicals;
R12, R13, R14, and R15 are independently selected from hydrogen, halo, and organo radicals; and
n is an integer having a value of from 1 to 4; and
(c) a polysiloxane having at least two functional groups per molecule with which said first and second silanes are cappingly and non-hydrolyzingly reactive;
wherein;
(1) the first and second silanes together are provided in sufficient quantity relative to said polysilxane to non-hydrolyzingly react with substantially all of the cappingly reactive functional groups of the polysiloxane, and (2) the first silane constitutes from about 50% to about 98% by weight of the total weight of the first and second silanes.

n is an integer having a value of from 1 to 4;
(b) a second silane of the formula: ##STR2## wherein: R11 and R16 are non-polymerizable groups and are independently selected from halo and organo radicals;
R12, R13, R14, and R15 are independently selected from hydrogen, halo, and organo radicals; and
n is an integer having a value of from 1 to 4; and
(c) a polysiloxane having at least two functional groups per molecule with which said first and second silanes are cappingly reactive;
wherein: (1) the first and second silanes together are provided in sufficient quantity relative to the polysiloxane to react with substantially all of the cappingly reactive functional groups of the polysiloxane; and (2) the first silane constitutes from about 50% to about 98% by weight of the total weight of the first and second silanes.

26. A silicone composition, comprising:
-
a polysiloxane having at least two acryloxy-reactive functional sites per molecule; and a composition comprising capping species non-hydrolyzingly reactive with said functional sites of said polysiloxane, including acryloxy functionality and non-polymerizable functionality, which when non-hydrolyzingly reacted with said polysiloxane functional sites are cappingly effective therefor to provide acryloxy functionality and non-polymerizable functionality on said polysiloxane, such that the acryloxy functionality on the capped polysiloxane functionalizes from about 50% to about 98% of the reactive functional sites on the polysiloxane, and the non-polymerizable functionality functionalizes the remaining reactive functional sites on the polysiloxane. - View Dependent Claims (27, 28, 29)
