Abstract
Polymerization of liquid crystalline bifunctional monomer N-{{ω-{4-[4-(11-acryloyloxy)undecanoxybenzoyl]biphenyleneoxy} alkyl}}-3,4-dimethylpyrrole gave a side-chain liquid crystalline polyacrylate containing 3,4-dimethylpyrrole group. Liquid crystallinity was determined by DSC and optical polarizing microscope measurements. The monomers having pentylene, hexylene, and decylene as the alkylene spacer group between the mesogenic unit and the 3,4-dimethylpyrrole group exhibited smectic and nematic phases on the heating and cooling stages. The radically polymerized polyacrylate derivatives containing the 3,4-dimethylpyrrole group showed nematic phases on the heating and cooling stages. These polymers are the first example of side-chain liquid crystalline polymers containing 3,4-dimethylpyrrole as functional group for further reaction. © 2000 John Wiley & Sons, Inc.
