ABSTRACT:
Systems for initiating the polymerization of acrylic monomers comprising (1) organoborane-amine complexes and (2) bireactive decomplexers preferably comprising at least one free-radically polymerizable group and at least one amine-reactive group in the same molecule. The decomplexer is capable of forming a covalent bond with both the acrylic monomers and amine complex, resulting in a reduced level of mobile constituents. Furthermore, when the organoborane amine complex of the initiator system comprises a polyamine compound, polymerized acrylic compositions having improved solvent resistance are advantageously provided.
