  • Organoborane amine complex polymerization initiators and polymerizable compositions
    Patent number: 6762260
    Abstract: The invention is a two part polymerizable composition comprising in one part an organoborane amine complex and one or more compounds containing ring opening heterocyclic moieties, and in a second part, compounds capable of being polymerized by free radical polymerization, a catalyst capable of polymerizing compounds containing ring opening heterocyclic moieties and optionally a component that will decomplex the organoborane amine complex. In one embodiment the invention is a two phase system comprising a first phase containing one or more polymers prepared from the compounds which polymerize by free radical polymerization and a second phase comprising polymerized or partially polymerized compounds derived from one or more compounds containing ring opening heterocyclic moieties.
    Type: Grant
