Abstract
New nematic liquid crystal (LC) ester mixtures with relatively short average molecular lengths are made by including one or more binary sets of components which have identical, or nearly identical, molecular lengths. Undesirable solids solution phase effects are avoided by either utilizing appreciable asymmetry in the alkyl end groups or by combining LC esters of different classes.
