Abstract:
A living radical polymerization process, which comprises contacting a mixture of (a) a living free radical initiator having the formula Râ€”[Oâ€”Oâ€”Bâ€”&phgr;1(-&phgr;2)]n, wherein n is from 1 to 4, R is a hydrogen or a linear, branched or cyclic alkyl radical having a molecular weight from 1 to about 500, and &phgr;1 and &phgr;2, independently, are selected from aryl radicals, based on phenyl or substituted phenyl groups, with the proviso that &phgr;1 and &phgr;2 can be the chemically bridged to each other with a linking group or with a direct chemical bond between the two aryl groups to form a cyclic ring structure that includes a boron atom, with (b) at least one free radical polymerizable monomer at ambient temperature to produce a polymer having a molecular weight distribution (Mw/Mn) of less than about 1.5.
