Abstract
The present invention discloses a water dispersible polymer particle stabilized by a hydrophobically capped oligomeric acrylamide dispersant. The present invention also discloses 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 said organic phase to yield polymer particles stabilized with hydrophobically capped oligomeric acrylamide. Also disclosed in the present invention is a heterogeneous method for forming polymer particles comprising providing a water immiscible organic dispersed in a continuous water phase, polymerizing said organic phase, and adding bydrophobically capped oligomeric acrylamide to yield polymer particles stabilized with hydrophobically capped oligomeric acrylamide.
