Abstract:

Disclosed herein are inversion systems and methods of diluting w/o lattices including about 10 wt % to 80 wt % of a water soluble polymer. Using the inversion systems and methods described herein, dilution of w/o lattices is carried out in a single step to form dilute lattices having 10,000 ppm or less polymer; the dilute lattices form polymer solutions with no further addition of mixing force or water. The solution viscosities of the polymer solutions obtained using the systems and methods of the invention are at least about 80% of solution viscosity expected in the absence of shear.
