    摘要: A method for forming a functionalized latex polymer includes polymerizing a heterogeneous dispersion of water insoluble monomers in water, thereby forming a latex polymer. An at least partially water soluble halogenated non-ionic group is reacted with the latex polymer, whereby a halogen is displaced from the non-ionic group, thereby forming an at least partially water soluble non-ionic group that attaches to the latex polymer.
