    摘要: 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.

    摘要: Compositions comprising cyclophane metal complexes, methods for polymerization using such cyclophane metal complexes as catylysts and polymer compositions produced by such methods. Examples of polymers that may be manufactured by these methods incude polyethylenes and polyolefins. The cyclophane metal complexes of this invention are stable at high temperatures and thus may be used to catalyze polymerization reactions that occur fully or partially at high temperatures (e.g., temperatures above 50° C.).
