Abstract

The isothermal crystallisation from the nematic phase of five thermotropic liquid crystalline TRm polyesters formed from two mesogenic p-oxybenzoyl diads alternately flanked by a trioxyethylene segment and a polymethylene spacer of variable length (m = 6-10) was investigated. The melting behaviours, thermodynamic melting temperatures and crystallisation kinetic parameters are discussed in terms of the polymer structure. The activation energy for the formation of critical nuclei proved to be dependent on the inherent flexibility and parity of the spacer.
