    摘要： Some variations provide an oligomer composition comprising: polarizable first thermotropic liquid-crystal oligomer molecules (preferably urethanes or ureas) containing first triggerable reactive end groups, wherein the first triggerable reactive end groups are selected from the group consisting of hydroxyl, isocyanate, blocked isocyanate, acrylate, epoxide, amine, vinyl, ester, thiol, conjugated diene, substituted alkene, furan, maleimide, anthracene, and combinations thereof, and wherein the polarizable first thermotropic liquid-crystal oligomer molecules are characterized by a weight-average molecular weight from about 200 g/mol to about 10,000 g/mol; optionally, a plurality of polarizable second thermotropic liquid-crystal oligomer molecules containing second triggerable reactive end groups, wherein the second triggerable reactive end groups are capable of reacting with the first triggerable reactive end groups; and optionally, a reactive coupling agent capable of reacting with the first triggerable reactive end groups. Methods are described for converting the oligomer composition into an anisotropic thermally conductive polymer. Many commercial uses are disclosed.
