Optically active vinyl polymers containing fluorescent groups—4: Synthesis and properties of copolymers of 9-vinylcarbazole with (−)menthyl vinyl ether

Abstract

9-Vinylcarbazole (1) has been copolymerized with (−)menthyl vinyl ether (2) by a conventional cationic catalyst [Al(C 2H 5)Cl 2] in CH 2Cl 2 at −78°. Reactivity ratios were estimated using a relatively new method valid up to high conversions. Chiroptical properties, including differential dichroic adsorption (Δε) of the various copolymers, have been studied in an attempt to investigate correlations between physico-optical properties, and the chemical compositions, distributions of monomeric units and stereoregularity of the copolymerization products.
