Abstract: Liquid crystalline hydroquinone-3,4′-biphenyl dicarboxylate polyesters, and methods of making them. The polyesters may be melt processed at a temperature below the thermal decomposition temperature and the isotropic temperature, and may form a liquid crystalline glass phase. The polyesters may be formed by polycondensation of hydroquinone or a hydroquinone derivative with 3,4′-biphenyl dicarboxylic acid.

Abstract: A block copolymer comprising a PAO block derived from alpha-olefin monomer(s) having a carbon backbone comprising more than six (6) carbon atoms per molecule and a poly(alkyl methacrylate) block derived from alkyl methacrylate monomer(s) having an alkyl group comprising at least six (6) carbon atoms forms micelles in hydrocarbon solvents and lubricant oil base stocks with large space volume even at low overall molecular weight. The block copolymer of this disclosure is particularly advantageous as viscosity modifier for lubricant oil compositions.
