Abstract
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.

A method for forming a functionalized latex polymer, comprising:
- polymerizing a heterogeneous dispersion of water insoluble monomers in water, thereby forming a latex polymer;
- and
- reacting an at least partially water soluble halogenated non-ionic compound with the latex polymer, whereby a halogen is displaced from the halogenated non-ionic compound, thereby forming an at least partially water soluble non-ionic group that attaches to the latex polymer.
A method for forming a functionalized latex polymer, comprising:
- forming an at least partially water soluble halogenated non-ionic compound by incorporating a halogen into a non-ionic compound having an alcohol end group;
- polymerizing a heterogeneous dispersion of water insoluble monomers in water, thereby forming a latex polymer;
- increasing a pH of the latex polymer to a level ranging from about 7 to about 11 by exposing the latex polymer to a base;
- and
- reacting the at least partially water soluble halogenated non-ionic compound with the latex polymer, whereby a halogen is displaced from the halogenated non-ionic compound, thereby forming an at least partially water soluble non-ionic group that attaches to the latex polymer.
