Abstract

See full text

The present invention is directed to the use of a quaternized derivative of polyisobutylene as stabiliser in inverse emulsions like inverse emulsions used for a reverse-phase emulsion polymerisation process, e.g. for the polymerisation of acrylamide and ethylenically unsaturated cationic monomers. Such emulsions are e.g. used as flocculant for waste water treatment. The present invention is further directed to inverse emulsions comprising a quaternized derivative of polyisobutylene. The inverse emulsions have sufficiently low viscosity and sufficiently high shear stability. The present invention is further directed to an inverse emulsion polymerisation process, wherein the inverse emulsion comprises a quaternized derivative of polyisobutylene.
