摘要： The invention pertains to water-dissipatable polymers comprising lipophilic polymers having pendant sulfonic acid salt groups and, optionally, pendant nonionic groups, methods of making such water-dissipatable polymers and the use of such polymers in aqueous systems, including aqueous coating compositions. The invention also pertains to addition polymer polyols having such pendant sulfonic acid salt groups and, optionally, pendant nonionic groups, their methods of manufacture and their use in aqueous systems, including aqueous coating compositions. The polymers of the invention may be used as, for example, binders, emulsifying agents and dispersing agents in aqueous systems, especially aqueous coating compositions.

摘要： The invention pertains to a polymer obtainable from the steps: polymerizing a mixture, that is substantially free or organic solvents, of ethylenically unsaturated monomers which consist for at least 70% of methacrylates, and which comprises specific chain transfer agents, α-methylstyrene dimer being preferred, to form a first polymer, aqueous emulsion polymerizing a mixture comprising ethylenically unsaturated monomers in the presence of the first polymer to form a dispersion of a water-insoluble second polymer, wherein these steps are preferably performed in the absence or the substantial absence of a surfactant.
