Abstract:	9-Vinylcarbazole (1) has been copolymerized with (?)menthyl vinyl ether (2) by a conventional cationic catalyst [Al(C₂H₅)Cl₂] in CH₂Cl₂ 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.
