Abstract
A complex comprises organoborane and polyamine. The polyamine is the reaction product of a diprimary amine-terminated material and a material having at least two groups reactive with primary amine. The complexes are useful in systems for initiating the polymerization of acrylic monomer, which systems further include a material reactive with amine. Polymerizable acrylic monomer compositions useful as adhesives can be prepared.
