摘要： The invention relates to branched organopolysiloxanes and to their preparation and use. A branched organopolysiloxane is prepared by the reaction of an alkoxysilane with a substantially linear organopolysiloxane containing at least one hydroxyl or hydrolysable group bonded to silicon, in the presence of a phosphazene catalyst. The branched organopolysiloxanes obtained can be suitable for use in a moisture curable sealant composition capable of curing to a high modulus seal, with less tendency to gel than when using other siloxane polycondensation catalysts. Phosphazene catalysts also have the advantage that the content of undesired low molecular weight cyclic silicones in the polymerisation product is low.

摘要： This invention relates to the polymerization of organopolysiloxanes to form organopolysiloxanes of increased molecular weight and to the organopolysiloxane compositions thus produced. The organopolysiloxane is in admixture with a molten wax during the polymerization, thereby forming a blend of the wax with an organopolysiloxane of increased molecular weight. After the polymerisation reaction is completed, the reaction product can be cooled below the solidification temperature of the wax, for example down to room temperature. This yield a paste-like solid blend which is a very intimate dispersion of wax in organopolysiloxane or vice versa. The dispersion is surprisingly stable.

摘要： Silicone pressure sensitive adhesive (PSA) compositions and methods for their preparation are provided. In one embodiment, PSAs are formed from a silicone polymer mixture by condensation polymerization of low viscosity polyorganosiloxanes in inert solvents and/or silicone fluids, and optionally adding a silicone resin (MQ) during polymerization. The silicone polymer mixture formed may also be mixed with a silicone resin (MQ) and bodying catalyst, and bodying is allowed to continue until the desired reaction product is formed.

摘要： This invention relates to aqueous emulsions comprising a polyorganosiloxane and a wax, and to methods of production of such emulsions. The emulsions are of the type oil-in-water. An organopolysiloxane is polymerized in admixture with a molten wax, thereby forming a blend of the wax with an organopolysiloxane of increased molecular weight, and the said blend of polymer and molten wax is emulsified in water in the presence of a surfactant. The emulsions are useful in personal care applications such as on hair, skin, mucous membrane or teeth. The emulsions are also useful in applications such as paints, water based coatings, textile fibre treatment, leather lubrication, fabric softening, fabric care in laundry applications, homecare, release agents and oil drag reduction.

摘要： This invention relates to organopolysiloxane (silicone) compositions containing an active material chosen to have a desired effect in the composition, such as a perfume, sunscreen, vitamin, drug, biocide, pest repellent, catalyst or cooling agent. The active material is generally an organic material which is not silicon-containing. In particular the invention relates to such composition in which the release of the active material from the composition is inhibited or controlled. The active material is incorporated in a blend of a wax with an organopolysiloxane which has been formed by polymerization in the presence of the wax. It was found that by polymerizing an organopolysiloxane in admixture with molten wax, a stable wax silicone dispersion is obtained which allows ready incorporation of an active material such as a perfume and which releases the perfume only slowly, and may be controlled to release the perfume or other active material in desired circumstances.
