    • A method of reducing unreacted monomer in a water-soluble or water swellable polymer comprising the steps, i) applying an ultraviolet initiator to the surface of the polymer and ii) irradiating the polymer with ultraviolet light, wherein the ultraviolet initiator is dissolved or dispersed in a liquid medium and in which the liquid medium comprises an organic compound. The method is useful for reducing in the amount of unreacted acrylamide in polyacrylamide. Also claimed is a liquid initiator composition comprising, i) an ultraviolet initiator, and ii) a liquid medium comprising an organic compound. The initiator system is useful for applying to the surface of a polymer, such as polyacrylamide, in the removal of unreacted monomer, such as acrylamide.
    • 一种降低水溶性或水溶胀性聚合物中未反应单体的方法,包括以下步骤:i)将紫外线引发剂施加到聚合物的表面,和ii)用紫外光照射聚合物,其中紫外线引发剂溶解或分散在 液体介质,其中液体介质包含有机化合物。 该方法可用于减少聚丙烯酰胺中未反应的丙烯酰胺的量。 还要求的是液体引发剂组合物,其包含i)紫外引发剂,和ii)包含有机化合物的液体介质。 引发剂体系可用于在除去未反应的单体如丙烯酰胺之类的聚合物如聚丙烯酰胺的表面上。
