Zusammenfassung:Water-in-oil latices of water soluble or dispersible polymers and methods of using the same are presented. The latices include phosphorus functional inversion agents that provide rapid and complete inversion of the latices under conditions wherein the water source used to invert the latex is provided at high temperature, or includes a high level of total dissolved solids, or is both high temperature and high total dissolved solids.
