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.
