摘要:
The present invention relates to novel polycarbonate polyorganosiloxane and/or polyurethane polyorganosiloxane compounds, method for the manufacture thereof, use thereof, functional formulations containing them, precursors for the production thereof, and reactive compositions that contain said precursors.
摘要:
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.
摘要:
Composition of comprising nano metal oxide/hydroxide particles and a polyorganosiloxane having increased refractive index, processes to cure these compositions for making transparent coats, shaped articles by an extrusion or molding process having a refractive index above the refractive index of the polyorganosiloxane. Use of the cured polyorganosiloxane compositions as optical devices, coats, lenses or light guides.
摘要:
An asymmetrically substituted polyorganosiloxane comprising at least one or more siloxane blocks and different reactive groups at each end of the siloxane chain, e.g. an alkoxysilyl, alkenyl, epoxy, hydroxyaromatic or an ionic substituent. Each polyorganosiloxane block has substantially a monomodal chain length distribution and is suitable for the use as a surface modifying agent for organic or inorganic particles, as a surface active material, and/or as a compatibilizer in compositions having more two or more non-miscible phases.
