Liquid Crystalline Copolymers of Monomer-Pairs Containing Mesogenic Units Which Exhibit Constitutional Isomerism.

Abstract

The synthesis and characterization of side-chain liquid crystalline copolymers obtained from a monomer pair containing a mesogenic unit which exhibits constitutional isomerism are presented. The particular example described refers to copolymethacrylates obtained from 4-hydroxy-4'-methoxy-alpha-methylstilbene and 4-methoxy-4'-hydroxy-alpha-methylstilbene containing six methylenic units presents a nematic mesophase, while the polymer containing eleven methylenic units presents a smectic A or C mesophase. None of these polymers exhibited side-chain crystallization.
