摘要: Disclosed is a polymer material of low relative permittivity obtained through copolymerization monomer composition that contains, as monomers, fumaric diester and an epoxy group-having (meth)acrylate. The bonds or adheres well to metal conductor layers, and, after crosslinked, it patternable. In addition, has good electric properties permittivity, dielectric loss tangent insulation, heat resistance.
