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.

Devices for and method of generating coherent second harmonic light radiation. The devices comprise a laser source of coherent light radiation at a fixed fundamental frequency, crystalline 5-chloro-2-nitroaniline that crystallizes in a non-centrosymmetric configuration, means for directing the output radiation of the laser onto the 5-chloro-2-nitroanilane, and output means for utilizing the second harmonic frequency.
