Abstract:
The invention relates to a method of producing reverse microemulsions from cationic copolymers. The inventive method consists in the polymerisation of a non-ionic monomer and a cationic monomer into a reverse microemulsion. Said polymerisation is carried out in the presence of an auto-reversible surfactant system in contact with an aqueous suspension or solution which can thermodynamically stabilise the system. According to the invention, the non-ionic monomer/cationic monomer mass ratio is included between 99:1 and 20:80.
