Abstract:

The synthesis and characterization of polyp-vinylbenzyl ethers containing 4-oxybiphenyl or 4-oxy-4 methoxybiphenyl mesogens or a 4-oxy-4-methoxybiphenyl mesogen which is connected to the benzyl ether group through one, two or three oligooxyethylene units, are presented. The first two polymers exhibit a nematic mesophase, while the last three, a highly ordered smectic mesophase.
