ABSTRACT A dispersion of water soluble or water swellablepolymer in water immiscible liquid is made by reversephase polymerisation utilising a dispersing systemcomprising a polymerisation stabiliser and the resultingdispersion, optionally after dehydration, may bedistributed into water utilising a distributing system. The dispersing system or the distributing system, orboth, includes at least one non-ionic compound selectedfrom C6-12 alkanols, C4-12 alkylene glycol monoethers andtheir C1-4 alkanoates, C6-12 polyalkylene glycolmonoethers and their C1-4 alkanoates and benzyl alcohol. Novel dispersions are made by reverse phasepolymerisation and, in particular, include a non-ioniccompound selected from C4-12 alkylene glycol monoethers,their C1-4 alkanoates and C6-12 polyalkylene glycolmonoethers and their C1-4 alkanoates. When the polymeris water soluble a solution of it in water can be made bydistributing the dispersion into water.
