Abstract
A water-borne latex of homopolymer poly(2-hydroxy-ethtyl methacrylate) (PHEMA) prepared by using 2-hydroxyethyl methacrylate (HEMA) through an emulsion polymerization process, the composition thereof comprising: monomer HEMA, water, emulsifier and initiator; the emulsifier being a single ionic surfactant or a mixture emulsifier with polymeric colloids in which, the ionic surfactant is selected from alkyl sulfates, alkyl sulfonates, alkyl phenyl sulfonates, alkyl ammonium salts, or alkyl phenyl ammonium salts, the polymeric colloids are selected from modified starch, modified cellulose, synthetic colloids, semi-synthetic colloids; the initiator is a thermally decomposable initiator or redox initiator with low water solubility or low starting rate in an aqueous phase; the reaction temperature is 30-95℃ for a thermally decomposable initiator, or 5-35℃ for a redox initiator; the solid content of the obtained emulsion can reach 15 % by weight.
