WATER SOLUBLE POLYMERIC COMPOSITIONS

摘要

WATER SOLUBLE POLYMERIC COMPOSITIONS A homogeneous blend is formed of different water soluble polymer types, for instance of particular addition and condensation polymers, by forming one of the polymers from its monomeric starting material by polymerisation in a solution of the other polymer. The resultant solution has a concentration of above 10% but is homogeneous. It can be used as a bulk solution or can be dried to powder or can be present as a reverse phase dispersion. The composition can be used to treat an aqueous substrate such as an aqueous solution containing turbidity and/or suspended solids or an aqueous liquor containing solids to be conditioned.
