摘要：
A water-in-oil demulsifier is prepared by (a) reacting a high molecular weight polyalkylene glycol (PAG) with ethylene oxide (EO) to form a PAG/EO adduct, (b) esterifying the PAG/EO adduct with a diacid anhydride to form a diester, (c) reacting the diester with a vinyl monomer, and (d) additionally esterifying the product of step (c) with a polyhydric material.
