  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.

  Water soluble or water swellable polymeric material is made by forming a dispersion in a non-aqueous liquid of water absorbent seed particles formed from first monomer, absorbing an aqueous solution of water soluble ethylenically unsaturated second monomer into the particles and polymerising the second monomer to form the said polymeric material. The invention is of particular value in the production of irregularly shaped non-spheroidal highly absorbent polymeric particles suitable for use in diapers, or for the production of soluble polymers.

  水溶性或可遇水膨胀的聚合材料是通过以下方法制成的：在非水性液体中形成由第一单体形成的吸水性种子颗粒的分散体，将水溶性乙烯基不饱和第二单体的水溶液吸收到颗粒中，并使第二单体聚合形成上述聚合材料。本发明在生产不规则形状的非球形高吸水性聚合物颗粒（适用于尿布）或生产可溶性聚合物方面具有特殊价值。
