Abstract Low molar mass liquid crystal solvents with positive dielectric anisotropy exhibit an electrorheological (ER) effect such that the viscosity, , in the presence of a strong electric field, applied transverse to the flow, is larger than that, , in the absence of such a field. Dissolution of a liquid crystal polymer (LCP) enhances the magnitude of the ER effect by an amount, , which is...
A series of polyethers has been synthesized from 1-(4-hydroxy-4′-biphenyl)-2-(4-hydroxyphenyl) propane and α,ω-dibromoalkanes having both odd and even numbers of methylene units [TPP(n = odd)s and TPP(n = even)s]. These polymers exhibit multiple thermodynamic first-order transitions during cooling and heating which demonstrate little supercooling dependence at different rates. The transition thermodynamic...
