✦ Synopsis

Abstrae-The synthesis of polymerizable lipobiphenyls, the study of the kinetics of their radical polymerization giving comb-like polymers, and the study of the thermotropic behaviour of the polymers are reported. Utilization of all the information provided by X-ray diffraction diagrams showed that polymers with polyacrylamide main chains and lipobiphenyl side chains exhibit successively, between room temperature and isotropization temperature, two mesophases: an ordered tilted double layer smectic phase S12, and a disordered tilted double layer smectic phase SC2.
