    摘要： Copolymers of zwitterionic monomer, especially 2-methacryloyloxyethyl-2′-trimethylammoniumethyl phosphate inner salt, and hydrophobic comonomer, especially dodecylmethacrylate, are made in a monomer starved polymerization process in which solutions of monomers are fed to the reaction vessel in which initiator is present over an extended period. The copolymers have improved compositional uniformity and provide better coatings on a range of substrates. The novel copolymers can be distinguished from prior art batch type bulk solution polymerization polymers of the same monomer composition by solubility characteristics especially in alcohol/water mixtures. Particularly preferred coating compositions comprise an alcohol:water mixture containing around 20 to 40% by volume alcohol.
