cyclobutane adducts of strong donor olefins and strong acceptor olefins, 1,1,2,2-tetracyano-3-ethoxycyclobutane (1a) and dimethyl 2,2-dicyano-3-ethoxycyclobutane-1,1-dicarboxylate (1b), with 2-oxazolines (2) are described. In the reaction of 1b with 2-methyloxazoline (2b), the alternating copolymer of 1b and 2b, the 1:1:1 periodic terpolymer of dimethyl 1,1-dicyanoethylene-2,2-dicarboxylate, vinyl ether, and
强供体烯烃和强受体烯烃,1,1,2,2-四氰基-3-乙氧基环丁烷(1a)和2,2-二氰基-3-乙氧基环丁烷-1,1-二羧酸二甲酯(1b)的环丁烷加合物的自发共聚),描述了2-恶唑啉(2)。在的反应1B与2-甲基恶唑啉(2B)中,交替共聚物1B和2B中,1:1:二甲基1,1-二氰基乙烯-2,2-二羧酸酯,乙烯基醚,和的1周期三元共聚物2b中,为获得。环丁烷1a也与2b反应生成富含1a的共聚物
