The Raman scattering on a novel liquid crystal side chain polymer

poly-2

5-bis (p-meth-oxybenzoyloxy) styrene

has been performed. We observed that the characteristic Raman sp-ctra of the vinyl group in the monomer changed much deeply in the polymer

especially for the Raman line correponding to the C=C of the vinyl group which disappeared completly in the polymer. Contrast with that

the Raman spetra of the rest group did not present any substantial difference between the monomer and the polymer. These experimental facts show-ed that the vinyl group of the monomer was tranfered to the polymeric backbone while the chemical structure of the mesogenic unit in the monomer remained after the polymerization

and also conformed that it was successful in the synthesis of a liquid crystal side chain plymer without a flexible spacer between the mesomorphic unit and the molecular main chain.
