ABSTRACT A dispersion of water soluble or water swellable polymer in water immiscible liquid is made by reverse phase polymerisation utilising a dispersing system comprising a polymerisation stabiliser and the resulting dispersion, optionally after dehydration, may be distributed into water utilising a distributing system. The dispersing system or the distributing system, or both, includes at least one non-ionic compound selected from C6-12 alkanols, C4-12 alkylene glycol monoethers and their C1-4 alkanoates, C6-12 polyalkylene glycol monoethers and their C1-4 alkanoates and benzyl alcohol. Novel dispersions are made by reverse phase polymerisation and, in particular, include a non-ionic compound selected from C4-12 alkylene glycol monoethers, their C1-4 alkanoates and C6-12 polyalkylene glycol monoethers and their C1-4 alkanoates. When the polymer is water soluble a solution of it in water can be made by distributing the dispersion into water.
