When flocculating an aqueous suspension of suspended solids using a high molecular weight synthetic polymeric flocculant the shear stability of the flocs is increased if the polymeric material includes polymeric particles of below 10 mu m dry size. The flocculated solids can therefore be subjected t ...

This invention relates to aqueous acidic solutions which are thickened by cationic polymer, the polymer being added to the solution in the form of particles below 10 mu m in size. The useful cationic polymers are formed from a water soluble cationic ethylenically unsaturated monomer or blend of mono ...

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 ...

Water absorbent particulate polymers and their uses are described. Friable aggregates may be made by bonding substantially dry polymer particles with an aqueous liquid and drying the aggregates. These aggregates can be broken down to the individual polymer particles upon mixing with an aqueous mediu ...
