Abstract
Cationic polymerization of mesogenic epoxides using hydroxyethyl metha crylate/BF3 as the initiator system led to novel polyether macromonome rs bearing a methacrylate functionality. These macromonomers exhibited nematic or smectic mesophases depending on the length of the alkoxy t ail of the aromatic mesogen. Low molar mass polymers obtained from the se macromonomers showed the same type of mesophases. However, with a h igh molar mass polymer a change from smectic to nematic was found.
