Abstract: A silicon-containing copolymer which includes zwitterionic linking groups with the general structures —N+(Y?)(Z)— or —N(Z*)— and repeating groups which can be divalent silicone moieties, divalent hydrocarbons or divalent polyethers. The copolymer can be used in personal care products, fertilizers and other agricultural products, pesticides, antifouling agents, and various waterborne coating formulations.

Abstract: The present invention is related to the preparation and use of moderately cross-linked (chin-extended), reverse (or “inverted”) surfactants, wherein the reverse surfactants comprise a polyether backbone with oligomeric or polymeric silicon-containing substitutions along the backbone. The present invention further describes crosslinked versions of the inverted surfactants, reaction products of alkenyl (allyl, vinyl, methallyl) functional copolymers (polyethers), silicone hydrides and cross-linking agents, which may be optionally reacted with water to react the remaining alkoxy groups. The crosslinking agent contains either SiH or Si-alkoxy groups or both. The compounds of the present invention exhibit only moderate cross-linking in order to be soluble or dispersible in appropriate solvents.
