ABSTRACT:
A homogenous 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 polyer. The resultant solution has a concentration of above 10% but is homogenous. It can be used as a bulk solution or can be dried to powder or can be present as a reverse phase dispersion.
