Inverse‐emulsion polymerizations of aqueous solutions of acrylamide (AM) in an isoparaffinic solvent were carried out using Span 80 as emulsifier. The conversions at the end of inverse‐emulsion polymerizations were investigated by HPLC methods. The conversion has been influenced by the initiator concentration, the monomer concentration and the reaction temperature. The molar masses were determined by viscosity measurements, size exclusion chromatography (SEC) and static light scattering. The influence of initiator concentration, monomer concentration and reaction temperature on the average molar mass of polyacrylamide (PAM) was studied.
