Abstract
A polymer composition is disclosed that comprises a polymer matrix containing at least one thermotropic liquid crystalline polymer and at least one hollow inorganic filler having a dielectric constant of about 3.0 or less at a frequency of 100 MHz wherein the weight ratio of the at least one thermotropic liquid crystalline polymer to the at least one hollow inorganic filler is from about 0.1 to about 10 and wherein the polymer composition exhibits a dielectric constant of about 4 or less and a dissipation factor of about 0.02 or less, as determined at a frequency of 10 GHz.
