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 aspartic acid ester-functional polysiloxanes, their use in the manufacture of curable compositions using polyisocyanate crosslinkers, in particular, in the manufacture of coating compositions, cured compositions obtained from said curable compositions and articles comprising the cured compositions.

Aspartic acid ester-functional polysiloxanes, their preparation and use thereof

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

Reactive functional siloxane compositions

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.
