ABSTRACT:
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.
