Abstract
A composition prepared by blending liquid crystalline polyesters and linear polyesters under reactive conditions in the presence of at least one poly(O- or N- epoxy alkyl substituted) cyclic amide, imide, or imidate; wherein the blend exhibits an anisotropic melt phase. Articles made from the composition have increased strength stiffness and improved drip characteristics. A preferred embodiment includes a polyalkylene terephthalate, a liquid crystalline polyester with structural units including p-benzoic acid and naphthoic acid, and triglycidyl isocyanurate.
