Claim 0:
1. A one-pot process of making a single-phase silicone-acrylic hybrid composition comprising the steps of:
(a) making an acrylic polymer solution by a free radical polymerization in an organic solution;
(b) adding (i) a silicone polymer and (ii) a catalyst to the acrylic polymer solution and reacting to form a silicone-acrylic hybrid solution;
(c) neutralizing the silicone-acrylic hybrid solution with a neutralization reagent,
(d) filtering any solid precipitates from the silicone-acrylic hybrid solution to form a single-phase silicone acrylic hybrid composition in solution;
wherein the ratio of the silicone polymer and the acrylic polymer is from 50:1 to 1:50,
wherein the silicon-acrylic hybrid composition comprises —Si—O—Si— covalent bond linkages between the silicone polymer and the acrylic polymer;
wherein the one-pot process is conducted in a single reaction setting; and
wherein the silicon-acrylic hybrid composition remains as a single-phase for over six months.
