ABSTRACT:
An energy-polymerizable composition derived from ingredients comprising: a cyanate ester monomer or oligomer comprising an organic radical bonded through aromatic carbon atoms to at least two --OCN groups; a low molecular weight polyalkylene glycol; and an organometallic compound in which at least one carbon atom of an organic group is bonded to a metal atom. The composition can be cured by at least one of thermal energy, radiation, and accelerated particles, to produce a cured, homogeneous composition.
