Synthesis of Benzocyclobutene-Capping Liquid Crystalline Poly(ester imide)s with Low Coefficient of Thermal Expansion and Dielectric Constant.

With the increase in the BCB capping group content (from 1.5 to 6.0 mol%), the T m of the LCPEIs showed a decreasing trend, but this trend was not large (194–186 °C), while the T g showed an increasing trend in a larger range (137–167 °C).
