Process for preparing copolymerizable macromolecular monomers having a substantially uniform molecular weight distribution

Abstract

Abstract This application discloses a process for preparing a copolymerizable macromolecular monomer comprising (a) polymerizing a vinyl-containing compound in the presence of an alkali metal hydrocarbyl anionic polymerization initiator to produce a monofunctional living polymer, (b) reacting said monofunctional living polymer with an alkylene oxide capping agent having eight or fewer carbon atoms to obtain a monofunctional alkoxide anion terminated macromolecular monomer, and (c) reacting said monofunctional alkoxide terminated macromolecular monomer with a halogen-containing compound which also contains a polymerizable moiety, said halogen-containing compound being a member selected from the group consisting of acrylyl halide, methacrylyl halide, vinyl-2-haloethyl ether, vinyl haloacetate, halomethylmaleic anhydride and its esters, allyl halide, methallyl halide, epihalohydrin, and vinylbenzyl halide to produce said macromolecular monomer having a copolymerizable end group, said copolymerizable macromolecular monomer being further characterized as having a substantially uniform molecular weight distribution such that its ratio of Mw/Mn is less than about 1.1, wherein Mw is the weight average molecular weight of the macromolecular monomer and Mn is the number average molecular weight of the macromolecular monomer.
