摘要： A polydiorganosiloxane having both a silicon bonded aliphatically unsaturated group and a silicon bonded poly(meth)acrylate polymer or copolymer is useful in a polyorganosiloxane hybrid pressure sensitive adhesive composition that cures to form a polyorganosiloxane hybrid pressure sensitive adhesive. The polyorganosiloxane hybrid pressure sensitive adhesive composition can be wet-cast or dry-cast on a substrate and cured to form a polyorganosiloxane hybrid pressure sensitive adhesive article. An adhesive article including the polyorganosiloxane hybrid pressure sensitive adhesive is also disclosed.

摘要： A process for producing a silicone pressure sensitive adhesive is shown and described herein. The process comprises reacting a MQ silicone resin with a polydiorganosiloxane in the absence of a solvent. The MQ silicone resin is a solid, solventless MQ resin. The reaction may be conducted in the presence of a catalyst, a chain extension reagent, or a combination thereof, and the resulting pressure sensitive adhesive can be dissolved in a solvent and the solids content adjusted. The present method provides a manner to provide a cleaner adhesive material that is free of unwanted materials such as aromatic solvents and also substantially free of cyclic siloxane impurities.

摘要： A composition forms a silicon-containing underlayer film, the composition being for forming a silicon-containing resist underlayer film that enables formation of a good resist pattern without pattern collapse even when having a thinner thickness compared to conventional products, such as a thickness of 10 nm or less. The composition for forming a silicon-containing underlayer film contains: [A] a polysiloxane having a weight average molecular weight of 1,800 or less as determined by gel permeation chromatography (GPC) analysis in terms of polystyrene, and the amount of a component having a molecular weight of more than 2,500 is less than 20% in an integral molecular weight distribution curve prepared by gel permeation chromatography (GPC) analysis in terms of polystyrene; and [B] a solvent.

摘要： A bio-electrode composition contains: (A) a polymer compound containing a repeating unit-a having a structure selected from the group consisting of salts of ammonium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide; and (B) a silicone compound having a polyglycerin structure. This bio-electrode composition is able to form a living body contact layer for a bio-electrode which enable quick signal collection after attachment to skin.

100 parts by mass of (A) an organopolysiloxane containing an alkenyl group,
0.2-20 parts by mass of (B) an organohydrogenpolysiloxane containing a hydrogen atom bonded to a silicon atom,
(C) a catalyst based on a platinum-group metal, the amount of which is 0.5-500 ppm in terms of platinum-group metal amount (in mass) with respect to the total mass of the components (A) and (B),
1-10 parts by mass of (D) a specific phenyl-group-containing organopolysiloxane,
1-25 parts by mass of (E) a specific nonfunctional dimethylpolysiloxane, and
(F) a specific benzotriazole derivative, the amount of which is 2-100 mol per mol of the platinum atoms contained in the component (C).
The oil-bleeding silicone rubber composition gives cured objects having improved heat resistance, without containing any of conventional additives for improving heat resistance.-
