Abstract
Prepolymer polyols containing mesogenic moieties useful as reactants for the preparation of resinous materials are disclosed. Synthesized by condensing a polyether polyol with bifunctional mesogenic diacids, or diesters, the compounds of the invention are characterized by their reasonably low melt temperature which renders them suitable as additive materials in polymeric molding compositions and as precursors for the preparation of resinous materials. The liquid crystalline properties of the prepolymers of the invention were found to depend on the type and molecular weight of the glycols and on the molar ratio between the glycols and the mesogenic reactant.
