A method and apparatus for removing an organosilicon component from a mixture are disclosed. The method and apparatus employ a copolymer of a di-alkenyl functional aromatic hydrocarbon and a polyorganosiloxane as the sorbent.

Method of depleting an organosilicon component in a mixture using a sorbent copolymer and apparatus for practicing the method

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.

Silicone acrylate compositions and methods of preparing the same

A multi-phase silicone acrylic hybrid visco-elastic composition prepared by polymerizing an ethylenically unsaturated monomer and a silicon-containing pressure sensitive adhesive composition comprising acrylate or methacrylate functionality in a first solvent in the presence of an initiator, removing the first solvent, and adding a second solvent to form the multi-phase silicone acrylic hybrid visco-elastic composition. Alternatively, a multi-phase silicone acrylic hybrid visco-elastic composition prepared by polymerizing an ethylenically unsaturated monomer and a silicon-containing pressure sensitive adhesive composition comprising acrylate or methacrylate functionality in a first solvent in the presence of an initiator, adding a processing solvent having a higher boiling point than the first solvent, applying heat to selectively remove a majority of the first solvent, removing the processing solvent, and adding a second solvent to form the multi-phase silicone acrylic hybrid visco-elastic composition. The phase arrangement of the multi-phase silicone acrylic hybrid visco-elastic compositions is selectively controlled by selection of the second solvent.

Silicone paste compositions are disclosed by combining a silicone organic elastomer gel with water or a hydrophilic solvent. The silicone paste compositions may further contain a personal or healthcare active. The silicone organic elastomer gel is prepared by reacting in a carrier fluid an organohydrogensiloxane with two polyoxyalkylenes, the first polyoxyalkylene having aliphatic unsaturation at both each molecular termini, and the second polyoxyalkylene having aliphatic unsaturation at one molecular terminal.

This invention provides a single phase silicone acrylate formulation that resists phase separation and includes (A) at least one of a silicone, an acrylate, and combinations thereof. The single phase silicone acrylate formulation also includes (B) a silicone acrylate hybrid compatibilizing agent including silicone functionality and (meth)acrylate functionality and that is the reaction product of a silicon-containing pressure sensitive adhesive composition, a (meth)acrylate, and an initiator. A method of minimizing phase separation of the single phase silicone acrylate formulation includes the step of combining (A) and (B) to form the single phase silicone acrylate formulation.
