The present invention relates to an oil-bleed self-bonding liquid silicone rubber composition having both self-bonding and self-lubricating capabilities. The oil-bleed self-bonding liquid silicone rubber composition exhibits self-bonding capability in particular to substrates that contain residual hydroxyl groups or other residual hydrosilyl-reacting groups on their surface, including polycarbonate, polyester, polyamide, polysulfone, polyurethane, phenolic resin, epoxy resin, cellulose, glass and the mixture thereof.

Oil-bleed self-bonding liquid silicone rubber composition

The present invention relates to a method for preparing a polysiloxane-polycarbonate block co-condensate, wherein a siloxane component containing both aliphatic and aromatic groups is used as a mediator. The invention also relates to a polycarbonate composition and also to the use of the special siloxane component for reducing the particle size distribution of the siloxane domains in a polysiloxane-polycarbonate block co-condensate.

Siloxane-containing block copolycarbonates having a small domain size

The present invention relates to an addition-curable silicone rubber composition having self-bonding capability. The addition-curable silicone rubber composition exhibits self-bonding capability in particular to substrates that contain residual hydroxyl groups or other residual hydrosilyl-reacting groups on their surface, including polycarbonate, polyester, polyamide, polysulfone, polyurethane, phenolic resin, epoxy resin, cellulose, glass and the mixture thereof.

Addition-curable silicone rubber composition

The subject of the present invention is a process for the production of polysiloxane-polycarbonate block cocondensates, wherein A) at least one polycarbonate is reacted in the melt with B) at least one hydroxyaryl-terminated polysiloxane with use C) of an additive which is selected from at least one from the group consisting of a siloxane containing aromatic substituents (component C1) and a polysiloxane-polycarbonate block cocondensate A) or polysiloxane-polycarbonate block cocondensate, which can also be different from A) (component C2).

Production of siloxane-containing block copolycarbonates by means of compatibilizers

The present invention relates to aqueous compositions comprising one or more silicones and a synergistic combination of anti-microbiological agents, to a process for preparing the aqueous compositions, and to the use of said aqueous compositions, in particular, for the manufacture of home care articles, household cleansing articles, fabric articles, cosmetic articles, hygienic articles, medical articles etc.

Aqueous silicone polymer compositions

Disclosed herein is a composition comprising amino-functional polysiloxanes of high purity and their preparation. Also disclosed herein is an aminoalkyl-functional polysiloxane, a process for purifying this aminoalkyl-functional polysiloxane, a process for preparing the composition, a use of the composition, a polyorganosiloxane-polyorgano block copolymer, a process for the preparation of a polyorganosiloxane-polyorgano block copolymer and a shaped, formed and/or extruded shaped article.

Aminosiloxanes of high purity

Disclosed herein are compositions, comprising linear polydiorganosiloxanes having enhanced reactivity and their use to prepare polydiorganosiloxane-polyorgano block copolymers.

Reactive functional siloxane compositions

Disclosed are processes for preparing sol-gel resins from phenolic compounds and aldehydes. The process includes reacting an hydroxylated benzene and a catalyst with an aldehyde to form a liquid storage stable intermediate. The storage stable intermediate may then be stored for a period of time before being utilized in a process to prepare the sol-gel resin, in either monolith or particle form, by subsequently reacting the intermediate with an hydroxylated benzene and a catalyst.

Method for preparing a sol-gel resin

Sol-gel resins can be prepared using one or two-step processes to produce small granules or pellets of resin that are easy to handle. The methods include agitating phenolic compounds and aldehydes in the presence of a catalyst and a solvent. The reactants are brought together over a period of time to avoid an undesirable buildup of heat within the reaction mass. Condensation of the material continues under agitation sufficient to knead the material as it gels. During this gelation, the material begins to form into smaller parts until particles, the shape of granules, are produced. The condensation continues to the degree that the material is no longer capable of sintering during packaging and storage. The material thus made can be easily discharged, packaged, portioned, and further processed.

Disclosed herein is a process for preparing a linear hydroxyaryloxy-functional polydiorganosiloxanes having controlled structures. The process includes the step of reacting a linear &#x3b1;,&#x3c9;-bisacyloxypolydiorganosiloxane with at least one bisphenolic compound, or hydroxy-functional oligomer thereof, in such a molar ratio that the phenolic groups in the bisphenolic compound or the hydroxy-functional oligomer thereof to the acyloxy groups in the &#x3b1;,&#x3c9;-bisacyloxypolydiorganosiloxane is less than 2.0. Also disclosed are hydroxyaryloxy-functional polydiorganosiloxanes produced from the process and the polysiloxane/polyorgano block copolymers made using the hydroxyaryloxy-functional siloxanes.

Process for producing functional siloxanes of controlled structure

Disclosed herein is a process for the production of a polysiloxane-polyorgano block copolymer. The process includes reacting a reaction mixture containing (a) an ester-functional polydiorganosiloxane and (b) a bisphenolic compound or a bisphenolic compound oligomer. This process has the advantage of yielding block copolymers with controlled block structures and avoiding the impurities that may be carried over from the conventional hydroxyaryloxy-terminated-polydiorganosiloxanes.

Polysiloxane-polyorgano block copolymers

The present invention relates on the use of 1,3-dihydroxyalkyl functionalized polyorganosiloxanes in compositions for the treatment of materials having a fibrous structure, such as leather, furs, textiles and paper. The invention further relates to a process for treating fibrous materials with waterproofing.

Hydrophobizing of fibrous materials with polyorganosiloxanes

The invention relates to a new method of coating substrates with an aqueous emulsion of a reactive silicone-based composition and a method of preparing said aqueous emulsion of said reactive silicone-based composition.
