METHOD OF PRODUCING REVERSE MICROEMULSIONS FROM NON-IONIC POLYMERS OR IONIC COPOLYMERS

摘要

The invention relates to a method of producing reverse microemulsions from non-ionic polymers or ionic copolymers. The inventive method consists in the polymerisation of non-ionic monomers, such as acrylamide, or a mixture of non-ionic monomers (acrylamide) and anionic monomers ((meth)acrylic acid or the salts thereof) 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/anionic monomer mass ratio is included between 100:0 and 40:60.
