Low dielectric, high heat-dissipation liquid crystal polymer composition for millimeter wave band, and method for producing same

A liquid-crystal-material monomer that is low-dielectric and high-heat-dissipating for a millimeter wave band, the liquid-crystal-material monomer being:

• a first monomer comprising a rod-shaped or plate-shaped mesogen core, a silane-based group, and a polymerization reactive group;
• or
• a second monomer comprising the rod-shaped or plate-shaped mesogen core and the polymerization reactive group;
• or
• a third monomer comprising the silane-based group and the polymerization reactive group,
• wherein the polymerization reactive group is one or more structures selected from structures of Formulae 34 to 43:
• wherein the R in each of the Formulae 34 to 43 is a substituent being at least one linking group, each of the at least one linking group having a structure of —(CH2)n-X—, where n is an integer from 1 to 12 and X is one selected from —O—, —S—, —SO2-, —NH—, —NHC(O)—, and —OC(O)—,
• wherein the rod-shaped or plate-shaped mesogen core or the silane-based group is connected to the polymerization reactive group by being bonded to the X or a terminal CH2 of the at least one linking group, and
• wherein, in the Formulae 35 and 36, when the at least one linking group includes an oxygen atom, the oxygen atom included in the at least one linking group and another oxygen atom of the Formula 35 or 36 bonded to the at least one linking group are positioned such that the oxygen atom included in the at least one linking group and the another oxygen atom are not linked consecutively.
