| 摘要 |
A process for the water-in-oil emulsion polymerization of at least one ethylenically-unsaturated monomer is disclosed wherein a water-in-oil emulsion of said monomer is polymerized in the presence of a first, highly reactive polymerization initiator until a small amount of polymer is present sufficient to provide a shear-stable emulsion, followed by completing the polymerization in the presence of a second, less reactive polymerization initiator. |
