Abstract
This disclosure relates to a curable composition that includes at least one maleimide-containing compound or benzoxazine compound, at least one low dielectric loss polymer or a hydrogenated derivative thereof, at least one filler, and at least one radical initiator. This disclosure also relates to using the composition to form a film, a laminate, and/or a circuit board.
