摘要： 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.

摘要： A process for preparing a block oligocarbonate is disclosed. The oligocarbonate conforms to ##STR1## where R denotes hydrogen or ##STR2## and where A denotes an aromatic carbonate structure conforming to ##STR3## where Ar is an aromatic radical, n is 2-6 and where B is the residue of an aliphatic polyol is disclosed. In the process a high molecular weight aromatic polycarbonate is reacted, in the melt and in the presence of a catalyst, with an aliphatic polyol. The block oligocarbonate is useful as a reactant in a process for the preparation of copolymers.
