Water-in-oil emulsions of monomers which form water-soluble polymers are polymerized in the presence of a biphase initiator system containing both an oil-soluble initiator and a water-soluble initiator or activator or alternatively a water-soluble initiator and an oil-soluble activator which results in polymers having improved performance characteristics. In addition, the system permits the satisfactory polymerization of monomers which could not have been reproducibly polymerized.
具有水溶性聚合物形成单体的油包水乳液在双相引发剂系统的存在下进行聚合,该系统包含既有油溶性引发剂又有水溶性引发剂或激活剂,或者是水溶性引发剂和油溶性激活剂,从而得到具有改善性能特征的聚合物。此外,该系统允许可靠地聚合单体,这些单体在过去无法被重复聚合。
