Abstract
Spontaneous copolymerizations of the cyclobutane adducts of strong don or olefins and strong acceptor olefins, 1,1,2,2-tetracyano-3-ethoxycyc lobutane (1a) and dimethyl 2,2-dicyano-3-ethoxycyclobutane-1,1-dicarbo xylate (1b), with 2-oxazolines (2) are described. In the reaction of 1 b with 2-methyloxazoline (2b), the alternating copolymer of 1b and 2b, the 1:1:1 periodic terpolymer of dimethyl 1,1-dicyanoethylene-2,2-dic arboxylate, vinyl ether, and 2b, was obtained. Cyclobutane 1a also rea cted with 2b to yield copolymer rich in 1a. (C) 1997 Elsevier Science Ltd.
