Notes:
2-(9-Carbazolyl)ethyl vinyl ether (1), a known vinyl monomer, was synthesized using a phasetransfer catalyst, and homopolymerized with BF3OEt2 or EtAlCl2.2-(9-Carbazolyl)ethyl 1-propenyl ether (2) was synthesized by transetherification of ethyl 1-propenyl ether with 9-(2-hydroxyethyl)carbazole in a yield of 34% as a mixture of 49% cis and 51% trans isomer. It was homopolymerized in 90% yield with EtAlCl2 in toluene at -25°C. Copolymerization of 1 or 2 with ethyl vinyl ether (3) were initiated with BF3OEt2 or EtAlCl2. The yields of copolymers were 78-93%, depending on the polymerization conditions. The solubility of both homo- and copolymers was found to be poor. The glass transition temperatures of poly(1-co-3) and poly(2-co-3) are much lower, than those of poly(1) and poly(2).
