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.
Claims24
An energy oligomerizable composition consisting essentially of at least one cyanate monomer or oligomer comprising an organic radical bonded through a carbon atom to one-OCN group 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.
