Abstract
A method of inverse emulsion polymerisation using an oil phase comprising a hydrocarbon oil obtainable from a gas to liquids process (a GTL oil) is described, in addition to an emulsion comprising a GTL oil and the use of a reaction product of an alk(en)yl substituted succinic anhydride and an amino alcohol to emulsify the emulsion.
Claims15
A method of making a polymer by inverse emulsion polymerisation which comprises the steps of:
- (i) forming an emulsion comprising an aqueous phase of polymerisable monomers dispersed in an oil phase comprising a GTL oil, wherein the GTL oil is a hydrocarbon oil obtained from a gas to liquids (GTL) process, wherein the emulsion also includes a surfactant which is obtained by reacting an alk(en)yl substituted succinic anhydride and an amino alcohol at a molar ratio of 1:at least 1.05, and
- (ii) polymerising the polymerisable monomers to form an emulsion of the aqueous phase comprising the resulting polymer, in the oil phase.
An emulsion comprising an aqueous phase and an oil phase, wherein a polymer is included in the aqueous phase, wherein the oil phase comprises a GTL oil and wherein the emulsion further comprises a surfactant which is obtained by reacting an alk(en)yl substituted succinic anhydride and an amino alcohol at a molar ratio of 1:at least 1.05.
