Abstract
Sodium dodecyl benzene sulfonate (DBSNa) surfactants, with a polydisperse and hyperbranched structure, combined with different rare earth metal salts generate highly water-dispersible Lewis acid surfactant combined catalysts (LASCs). This platform of new complexes promotes fast, efficient cationic polymerization of industrially relevant monomers in direct emulsion at moderate temperature. The process described here does not require high shearing, long polymerization time, or large catalyst content. It allows the reproducible generation of high-molar-mass homopolymers of pMOS, styrene, and isoprene, as well as random or multiblock copolymers of the latter two, in a simple and straightforward one-pot reaction. Old pot, best cooking! Well-known hyperbranched anionic surfactants (hard DBSNa) mixed together with rare earth metal salts, generate Lewis acid surfactant complexes. These complexes show remarkable efficiency in the (co)polymerization of, for example, styrene and isoprene into long and linear chains.
