    Abstract: A metal-clad laminate of the present invention comprises an insulating layer, and a metal layer that is present at least on one surface side of the insulating layer. The insulating layer is a laminate of at least three layers: a center layer, a first resin layer that is present on one surface side of the center layer, and a second resin layer that is present on the other surface side of the center layer. The center layer, the first resin layer and the second resin layer each contain a cured product of a respective resin composition. The elastic modulus of the cured product of the resin composition contained in the center layer is lower than the elastic moduli of both the cured product of the resin composition contained in the first resin layer and the cured product of the resin composition contained in the second resin layer.

    Abstract: A non-halogenated flame retardant filler having phosphorous-modified inorganic particles imparts flame retardancy to manufactured articles such as printed circuit boards (PCBs), connectors, and other articles of manufacture that employ thermosetting plastics or thermoplastics. Phosphorous-modified silica particles, for example, may serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant. In an exemplary application, a PCB laminate stack-up includes conductive planes separated from each other by a dielectric material that includes a non-halogenated flame retardant filler comprised of phosphorous-modified silica particles. In an exemplary method of synthesizing phosphorous-modified silica particles, a vinyl-terminated phosphorous-based monomer (e.g., a phosphorous based flame retardant functionalized to contain a vinyl functional group) is reacted with vinyl functionalized silica particles (i.e., the silica particle surface is functionalized to contain a vinyl functional group). Alternatively, hydrosilated terminated silica particles may be reacted with a vinyl-terminated phosphorous-based monomer to produce phosphorous-modified silica particles.
