Abstract:
1. A process for the preparation of an elastomeric gel characterized in that a polyorganohydrogensiloxane (A) having at least 3 Si—H groups per molecule is reacted with an unsaturated ester (B) of the formula —CH 2 —CH—A′-COOR, wherein A′ is selected from the group consisting of (i) an alkylene linkage having 1 to 16 carbon atoms, (ii) fluoro-substituted alkylene linkage, and (iii) a direct bond between the unsaturated moiety and the ester group and R is independently selected from the group consisting of (a) an alkyl group and (b) a fluoroalkyl group, a group (C) that is selected from (c) an alpha, omega-di-unsaturated hydrocarbon and (d) a alpha, omega-di-unsaturated fluorohydrocarbon, wherein at least the reaction between (A) and (C) takes place in a non-reactive material selected from the group consisting of (e) liquid organic material and (f) silicone material.
