Abstract
A self-inverting water-in-oil polymer emulsion having a low pour point is prepared by adding a pour point depressant, diol and triol in amounts effective to lower the pour point and inhibit skin formation on the emulsion. The emulsion may be prepared by adding a mixture of from about 0.05 to about 0.5 parts by weight of pour point depressant, from about 5.0 to about 100.0 parts by weight of diol and from about 5.0 to about 100.0 parts by weight of triol to 1.0 to 100.0 parts by weight of a self-inverting water-in-oil polymer emulsion.
