Abstract
A composition comprises organoborane polyamine complex and polyol. The composition can form a part of a polymerization initiator system that also includes polyisocyanate. The system can be used to initiate polymerization of acrylic monomer and to form a polyurethane/polyurea acrylic adhesive that has exceptionally good adhesion to low surface energy polymers.
