Silicone material obtained by a reaction between:—at least one organopolysiloxane (A) that has a molar mass of less than 70,000 g/mol, preferably less than 50,000 g/mol, and contains siloxyl units I.1 and I.2; and—at least one organic compound (B) carrying at least two carboxylic acid groups and having no unsaturation.

Silicone materials

Approaches are described for coating various flexible media, such as sheets of paper, synthetic polymer (polyolefin, polyester, etc.) sheets or fabric sheets, with a silicone on high-speed rolls. For example, an efficient method is described for minimizing and/or reducing mist formation when coating flexible supports with a liquid silicone composition precursor of crosslinked coatings. The coating process can be performed using a coating device that includes a roll operating at a high speed.

Method for preparing a silica grafted with an organosilicon compound

The present invention relates to a process for the production of an intermediate siloxane monomer and use of said monomer to produce high molecular weight linear polysilalkylenesiloxanes. The siloxane monomer is prepared by ring opening polymerization of a cyclic monomer of the structure in the presence of an acidic or basic ring opening polymerization catalyst; to form a mixture of siloxane monomers and linear oligomers. The linear oligomers are then extracted and discarded before a further step of ring opening polymerization using the aforementioned intermediate siloxane monomer mixture as the starting material. The second polymerization step is undertaken at a temperature within the melting point range of said siloxane monomer mixture. The intermediate, final product and methods of their manufacture are described.
