Abstract
Non-delaminating resinous compositions are prepared by blending at least one polyetherimide, at least one liquid crystalline polyester in an amount to provide lower melt viscosity, and a compatibilizing amount of at least one polyepoxy compound. The compositions may also contain a minor proportion of at least one non-liquid crystalline polyester such as poly(ethylene terephthalate) or poly(ethylene 2,6-naphthalenedicarboxylate).
