Abstract : The synthesis and characterization of poly(p-vinylbenzyl ether)s 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 oligo(oxyethylene) units, are presented. The first two polymers exhibit a nematic mesophase, while the last three, a highly ordered smectic mesophase.
