Abstract
An energy polymerizable composition comprising at least one cationically curable 5 or 6 membered 1,3 oxazyl heterocyclic compounds, including 1,3-oxazoline and 1,3-oxazine monomers or compound and a catalytically effective amount of an initiator comprising an organometallic compound, wherein such oxazoline homopolymers and copolymers exhibit increased rates of reaction, improved thermal stability, and higher glass transition temperatures. The resultant adhesive compositions are particularly useful in electronic applications, such as bonding to polyimide sheets or film, flexible circuits or fiber optic connectors.
