Emulsions having activating agents of alkoxylates of 6, 6-dimethylbicyclo [3.1.1] hept-2-ene-2-ethanol

Abstract

Disclosed is an emulsion useful in an inversion process. The emulsion is a water-in-oil emulsion and has an aqueous phase having a water-soluble polymer, an oil phase and an activating agent of the following formula: wherein n=0 to 10 and m=2 to 25 and the oxypropylene and oxyethylene units are of block distribution or intermixed in random or tapered distribution. Further disclosed is a process according to the following: a) providing an water-in-oil emulsion having a water-soluble polymer in the aqueous phase and the activating agent; b) introducing the emulsion into an aqueous medium and c) allowing sufficient time for the emulsion to invert. Further disclosed is another process according to the following: a) providing an water-in-oil emulsion having a water-soluble polymer in the aqueous phase; b) introducing the emulsion into an aqueous medium having the activating agent and c) allowing sufficient time for the emulsion to invert.
