Polyacrylamide is made by inverse emulsion polymerisation using an oil phase including at least one ester based oil, particularly a vegetable oil, using a primary emulsification system including a polymeric carboxylic surfactant; a low HLB emulsifier; and an oil phase structurant, particularly an ester wax such as beeswax. The use of the combination emulsifier enables the use of vegetable oils especially rape seed (including canola) oil as the continuous in the polymerisation step.
