ABSTRACT:
A thermotropic polymer, having an optically anisotropic phase, comprises recurring units of the formula (1) ##STR1## wherein R is a substantially linear organic substituent having a bulkiness factor greater than about 4 .ANG., and wherein X is a direct bond, --O--CH.sub.2).sub.n (n being an integer of 1 to 8) or --OCH.sub.2 CH.sub.2).sub.m (m=1, 2 or 3). The thermotropic polymer has a molecular weight distribution (Mw/Mn) of less than about 1.4.
