Abstract: Silicone acrylate copolymer composition, namely, silicone resin-acrylate copolymers and methods of preparing the same. The silicone acrylate composition may include a silicone resin coupled with an acrylate polymer via a linking group. The silicone acrylate composition may be formed by preparing an acrylate or a (meth)acrylate functional resin and carrying out acrylate polymerization in the presence of a functionalized resin. A silane-functional acrylate polymer may be prepared, followed by a reaction to couple a resin to the silane-functional acrylate polymer. The resulting copolymer may then be used as desired, e.g., added to a silicone and acrylate mixture to create a non-separating blend.
