ABSTRACT:
A water dispersible polymer particle stabilized by a hydrophobically capped oligomeric acrylamide dispersant or a heterogeneous method for forming polymer particles comprising providing a water immiscible organic phase comprising at least one monomer dispersed in a continuous water phase and a hydrophobically capped oligomeric acrylamide, and polymerizing the organic phase to yield polymer particles stabilized with hydrophobically capped oligomeric acrylamide. Also, a heterogeneous method for forming polymer particles comprising providing a water immiscible organic dispersed in a continuous water phase, polymerizing the organic phase, and adding hydrophobically capped oligomeric acrylamide to yield polymer particles stabilized with hydrophobically capped oligomeric acrylamide.
