POLYMERIZATION OF VINYL MONOMERS

摘要

Free radically polymerizable monomers may be polymerized using as an initiator a combination of a selected arylsulfonyl halide or alkylsulfonyl halide and a selected compound containing a lower valent transition metal atom. These polymerizations are sometimes living polymerizations, allowing control of polymer structure such as producing block copolymers and/or polymers with narrow molecular weight distributions. Useful monomers include styrenes and (meth)acrylate esters and amides. The products are useful as molding resins, for glazing, as film forming binders in coating compositions and have numerous other uses.
