| titleOfInvention |
Self-inverting water-in-oil emulsions of water-soluble polymers and a process for preparing the emulsions |
| abstract |
The emulsion comprises (1) a discontinuous aqueous phase containing a water-soluble polymer, which discontinuous phase is dispersed in a continuous oil phase where the emulsion contains an amount of inversion of a surfactant of inversion and an emulsifying amount of a water-in-oil emulsifying agent. The invention is characterized in that the emulsion is prepared by polymerization of a water emulsion in oil of a water-soluble monomer containing a portion of the inverting surfactant and by addition an additional amount of a reversing surfactant in the water emulsion in oil obtained from the water-soluble polymer following polymerization. The portion of inverting surfactants added before having completed the polymerization is sufficient to increase the degree of inversion when the emulsion is inverted in a continuous aqueous phase but it is less than the amount which would destabilize the monomeric precursor or the polymer emulsion. |
