Abstract: A shaped thermal filler particle has an elongate shape defined by a substantially planar first smooth surface and a second smooth surface that contacts the substantially planar first smooth surface along a planar closed path. The planar closed path has a length to width ratio of at least 1.5. The shaped thermal filler particle has a maximum linear dimension normal to the planar first smooth surface that is less than or equal to one half of the length of the closed path. A thermally conductive composition comprises from 1 to 95 percent by volume of the shaped thermal filler particles dispersed in a binder. An assembly comprises a heat source, a heat sink, and the thermally conductive composition at least partially sandwiched between the heat source and the heat sink.

Abstract: An adhesive composition is described comprising unpolymerized cyclic olefin, a ring opening metathesis polymerization (ROMP) catalyst or precatalyst thereof, and one or more adhesion promoter polymers. In one embodiment, the adhesion promoter is a polyolefin comprising maleic anhydride or silicon-containing moieties. In one embodiment, a combination of at least one polymeric polyisocyanate and at least one polyolefin comprising maleic anhydride or silicon-containing moieties provides a synergistic improvement. In another embodiment, a polymeric polyisocyanate adhesion promoter comprising oxygen atoms in the backbone has been found useful for bonding substrates such as polyamide, polyether ether ketone, or polyether imide. Also described are methods of bonding a substrate and articles, such as an electric battery cold plate assembly.
