Crosslinkable liquid crystalline polymer compositions for use as
dielectric materials in circuit materials, circuits, and multi-layer
circuits are disclosed. The crosslinkable liquid crystalline polymer
compositions comprise crosslinkable liquid crystalline polymers that
preferably comprise end groups selected from the group consisting of
phenyl maleimide, nadimide, phenyl acetylene, or combinations of the
foregoing. Additionally, the crosslinkable liquid crystalline polymer
compositions may further comprise particulate fillers and/or fibrous
webs. The crosslinkable liquid crystalline polymer compositions provided
improved electrical and mechanical properties.
