The invention is polymerizable composition comprising
a) an organoborane/amine complex wherein the organoborane is a trialkyl
borane or an alkyl cycloalkyl borane and the amine is selected from the
group of amines having an amidine structural component; aliphatic
heterocycles having at least one nitrogen in the heterocyclic ring; an
alicyclic compound having bound to the ring a substituent having an amine
moiety; primary amines which in addition to a primary amine have one or
more hydrogen bond accepting groups of an ether, polyether, thioether or
halogen wherein there is an alkylene chain of at least two carbon atoms
between the primary amine and the hydrogen bond accepting group, and
conjugated imines; and,
b) one or more of monomers, oligomers or polymers having olefinic
unsaturation; and optionally
c) an effective amount of a compound which causes the complex to
disassociate wherein the compound which causes disassociation of the
complex is kept separate from the complex until initiation of
polymerization is desired.
