Abstract
Improved emulsion breakers in the form of polyol acrylate polymers in water/oil emulsions have relatively high polymer contents and low inversion viscosities. The emulsion breakers can be prepared by mixing together acrylate monomer, polyol, water, liquid petroleum product, and emulsifier, followed by homogenization of the mixture; the latter is then subjected to free radical polymerization to polymerize the polyol and monomer in situ within the mixture.
