Abstract
A process for polymerization of vinyl monomers is described comprising polymerizing vinyl monomers in the presence of of an initiating system comprising (i) an organic sulfur compound and (ii) an onium salt catalyst. The present invention provides a novel method for living polymerization of vinyl monomers, which provides a high level of macromolecular control over the polymerization process and which leads to uniform and controllable polymeric products.
