DETERMINATION OF PHASE INVERSION POINT IN THE EMULSIFICATION OF POLYMERS*

Received Date: 15 May 1997

Phase inversion emulsification technique is a recently developed method to achievewaterborne dispersions of polymer resin. It is found that the electrica and rheologicalproperties of the system experience abrupt changes in the vicinity of the phase inversionpoint (PIP). Before PIP the system is a Newtonian fluid. At PIP the continuous phasetransforms from polymer resin to water phase with the result that the electrical resistanceof the system drops abruptly. Meanwhile, the system at PIP exhibits high visco-elasticity originated from the formation of a physical gel alike structure among the waterborne particles.Besides,the morphology evolution is observed by Scanning Electron Microscopy (SEM).
