Polymerization initiator systems containing aluminum compounds as curing inhibitors and polymerizable compositions made therewith

Abstract

The invention is directed to a composition comprising an organoborane / amine complex and an effective amount of an aluminum compound to inhibit curing of the organoborane / amine complex when used as part of a polymerization initiator system in a polymerizable composition containing one or more monomers, oligomers or polymers having olefinic unsaturation. The compositions of the invention can be used in polymerizable compositions, adhesive compositions and coatings compositions containing compounds having moieties which polymerize under free radical polymerization conditions.

Description

[0001] This application claims priority to US Patent Application Serial Nos. 60 / 548,828 and 60 / 548,987, filed February 27, 2004 and March 1, 2004, respectively.
