ABSTRACT:
This invention relates to an aqueous based process for the preparation of intercalated and/or exfoliated natural or synthetic clays using block copolymers in latex form containing at least one non-polar block and one or more cationic blocks, wherein the block copolymers are prepared by an emulsion controlled free radical polymerization method.
