Abstract
Polymerizable compositions having at least one cationically polymerizable monomer; an optional free radically polymerizable monomer; an energy-polymerizable catalyst system wherein the catalyst system comprises an organometallic complex salt; a thermally decomposable ester reaction product of a tertiary alkyl alcohol and an acid that forms a chelation complex with the metal ion of the organometallic complex salt; optionally, a peroxide. The polymerized compositions are useful as cured adhesive films, pressure sensitive adhesives, protective coatings, liquid adhesives, structural and semi-structural adhesives, and free standing films.
