Abstract
Abstract Steady flow viscosity data were obtained on a compound which exhibits a cholesteric liquid crystalline mesophase but does not contain the steroid moiety. The compound is (+)-2-methyl-butyl p-[N-(p-methoxybenzylidene)amino] cinnamate. This cholesteric liquid crystal rheology was found to the similar to that of the nematic class of liquid crystals. The material's liquid crystalline nature lowers its viscosity. A viscosity maximum in seen at the cholesteric-isotropic phase transition. This effect differs from that previously reported for cholesteric liquid crystals.
