| 摘要 |
The invention provides a polymer particle dispersion in an aqueous medium and a method of making the same, which comprises an emulsion polymerized polymer and a macroinitiator covalently bonded to the emulsion polymerized polymer. The living macroinitiator comprises a hydrophilic, pH-insensitive monomer in reacted form. The polymer particle dispersion may be obtained by reacting at least one monomer with the living macroinitiator and without a surfactant to effect polymerization of the monomer(s). The emulsion polymerized polymer may be comprised of at least one additional ethylenically unsaturated monomer in polymerized form. |
