Abstract
A composition is described comprising a cyclic olefin; a ring opening metathesis polymerization catalyst; and at least 40 wt. % of thermally conductive particles. The thermally conductive particles are selected such that the composition after curing has a thermal conductivity of at least 1W/M*K. In one embodiment, the thermally conductive particle comprises a combination of smaller and larger thermally conductive particles. In another embodiment, the thermally conductive particles comprise boron nitride particles. Also described are (e.g. structural) adhesives, methods of bonding and articles.
