Abstract: Reactive poly(fluoroalkyl-functional siloxane) oligomers, method of making the same, and compositions comprising the same are shown and described herein. The reactive poly(fluoroalkyl-functional siloxane) oligomers are is derived from a hydrolysable fluoroalkyl-functional silanes. Coating compositions comprising reactive poly(fluoroalkyl-functional siloxane) oligomer(s) may be used to form a coating or a film on a substrate and impart hydrophobic and/or oleophobic properties. The reactive poly(fluoroalkyl-functional siloxane) oligomer are more hydrophobic and oleophobic and show better chemical resistance than the hydrolysable fluoroalkyl-functional silane.

Abstract: A hydrophilic siloxane copolymer of siloxane and hydrophilic organic monomer/s The copolymers can be functionalized to make them capable of undergoing further polymerization by thermal or actinic radiations. The hydrophilicity of these polymers can be varied by varying the siloxane versus organic monomer ratio thereby going from water dispersible to soluble states. The siloxane content can be tuned accordingly in order to provide moderate to high oxygen permeability. These copolymers can be used as a single component curable composition which results in hydrogels to minimize the presence of leachable components thus by reducing the processing cost. The polymers may also find applications in personal care formulations as copolymers, film-formers, hydrogels, coating, emulsions/latex etc.

Abstract: A water swellable cross-linked elastomer and method of preparation is provided. The elastomer can advantageously be included in skin treatment compositions. Swellable elastomers in accordance with the invention are particularly well suited for inclusion in skin tightening cosmetic products. The elastomers can be formulated to form a film. When applied to skin, an elastomer in accordance with preferred embodiments of the invention can adhere to the skin and shrink as it dries. This can provide a skin tightening, lifting and wrinkle smoothening effect upon drying. This effect can temporarily mask the appearance of wrinkles.

Abstract: A thermally conductive silicone composition is shown and described herein. The thermally conductive silicone composition comprises (A) an ionically modified siloxane, and (B) a thermally conductive filler comprising a first filler and a second filler, where the first filler and/or the second filler comprises a plurality of filler types, the plurality of filler types differing from one another in terms of particle size and/or morphology. The ionically modified siloxane may function as a dispersing aid or wetter for efficient dispersion of thermal conducting organic and inorganic fillers to achieve high thermal conductivity.

Abstract: A continuous process for preparing a silylated polymer comprising a silylation step where a prepolymer having reactive functional groups, a first intermediate product, is reacted continuously with a silylating agent in an endcapping tubular reaction unit to form a second intermediate product, and where at least a portion of the second intermediate product is backmixed continuously with the first intermediate product to form the silylated polymer. The continuous process may further comprise a stabilization step, a quenching step or both a stabilization step and a quenching step.
