ABSTRACT:
An electrical circuit material having a conductive layer disposed a substrate, wherein the substrate comprises an organic or inorganic polymer comprising a covalently bound polyhedral silsesquioxane (POSS). The substrate may further comprise an additional dispersed POSS, any other fillers including fibrous webs. Use of covalently bound POSS allows for flame retardancy in compositions having acceptable dielectric constants and dissipation factors.
