ABSTRACT:
Exposing to visible light atom transfer radical polymerizations of vinyl monomers that use transition metal compounds often results in faster polymerizations and/or the need for less transition metal compound. Disclosed is a process for the polymerization of vinyl monomers by atom transfer radical polymerization using a first compound containing a transition metal and a second compound capable of radically transferring an atom or group to said first compound, wherein the improvement comprises, irradiating with visible light with an intensity of at least about 5 mW/cm.sup.2 a liquid in which said polymerization is taking place. The polymers made are useful for molding resins and coatings.
