Abstract: 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. Also disclosed are ester-functional polysiloxanes and polysiloxane-polyorgano block copolymers prepared by the process of the invention. These copolymers exhibit advantageous properties such as improved low temperature properties, improved rheological properties during molding, improved clarity, chemical, scratch resistance, and improved electrical insulation properties.
Abstract: The invention concerns polysiloxane compounds as W/O-emulsifiers, in textile softeners, antifoams, foam stabilizers and agriculture chemicals, in particular as W/O-emulsifiers for cosmetic uses.

Abstract: The invention provides silicone compositions (aminopolysiloxanes and/or ammonium polysiloxanes) which bind to fibrous substrates such as paper, and make the paper perceptibly softer and permit easy use of the paper in the paper production process, by leaving constant or improving hydrophilicity. The invention further provides polysiloxane-based compositions which can be flexibly adjusted to a given substrate and treatment condition by varying the ratios of the components of the composition.
