    • 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.
    • 本发明公开了一种由疏水封端的低聚丙烯酰胺分散剂稳定的水分散性聚合物颗粒。 本发明还公开了一种用于形成聚合物颗粒的非均相方法,其包括提供包含分散在连续水相中的至少一种单体的水不混溶的有机相和疏水封端的低聚丙烯酰胺,并聚合所述有机相以产生用疏水封端稳定的聚合物颗粒 低聚丙烯酰胺。 本发明还公开了一种用于形成聚合物颗粒的非均相方法,包括提供分散在连续水相中的水不混溶的有机相,使所述有机相聚合,并加入疏水性封端的低聚丙烯酰胺,以产生用疏水封端的低聚丙烯酰胺稳定的聚合物颗粒。
