ABSTRACT:
Disclosed are novel catalyst systems and method for curing a peroxide-curable ethylenically unsaturated (e.g. acrylic or vinyl) composition wherein the catalyst system is a combination of the peroxide curing agent and a Cu.sup.+1 activator or a combination of a peroxide curing agent and an activator system comprising a furfuryl alcohol and an acid catalyst. Also disclosed is a new catalyst system for curing ring compounds (e.g. epoxides) which comprises a combination of ferrocene and a diazonium salt of a Lewis acid. Preferred curable compositions are adhesives and especially acrylic adhesives and epoxy adhesives.
