Structure of Thermotropic Polyesters with Large Substituents.

Abstract

Thermotropic aromatic polyesters were aligned by drawing from nematic melts and by quenching in a magnetic field of 15 tesla and subsequently examined by x ray diffraction. The degree of alignment obtained depended slightly on the substituent (H, F, C1, Br, CH3, NO2) present with the highest degree of alignment observed when the arylsulfonyl substituted group contained in the para-position H or F and the lowest when it contained Br or CH3.
