【摘要】A composition comprising an oxyalkylated phenol-aldehyde resin and an acrylic acid component wherein the ratio by weight of oxyalkylated phenol-aldehyde resin to an acrylic acid component is in the range of from about 0.2:1 to about 4:1 is disclosed. The thus-obtained composition is employed in a process for demulsifying an oil and water emulsion which comprises adding the composition to the oil and water emulsion to thereby form a mixture and permitting a phase separation to occur, by known methods, e.g. settling, to thereby produce a hydrocarbon phase and a water phase. In an alternative embodiment, a process for emulsifying an oil and water emulsion which comprises adding an oxyalkylated phenol-aldehyde resin and an acrylic acid component to the oil and water emulsion to thereby form a mixture and permitting a phase separation to occur to thereby produce a hydrocarbon phase and a water phase is disclosed.
