Abstract
Energy polymerizable compositions comprising at least one cyanate monomer and as curing agent an organometallic compound are disclosed. The compositions are useful in applications requiring high performance, such as high temperature performance; in composites, particularly structural composities; structural adhesives; tooling for structural composities; electronic applications such as printed wiring boards and semiconductor encapsulants; graphic arts; injection molding and prepregs; and high performance binders.
Claims25
An energy polymerizable composition consisting essentially of at least one cyanate monomer or oligomer comprising an organic radical bonded through carbon atoms to at lest two --OCN groups and as curing agent a transition-metal containing organometallic compound in which at least one carbon atom of an organic group is bonded to the metal atom.
