Abstract
Polymeric compositions having a high dielectric constant are made from a thermotropic liquid crystalline and a ceramic having a dielectric constant which is greater than about 50 at a frequency of 1.0 GHz. The compositions have a dielectric constant of at least about 4, and preferably at least about 6. Preferred compositions also have a low loss tangent.
