Abstract
Anionic ring-opening polymerization of 2,8-dioxa-1-methylbicyclo[3.3.0]octane-3,7-dione (1b) was carried out. 1b had no homopolymerizability but copolymerized with glycidyl phenyl ether (2) to selectively give the corresponding alternating copolymer. IR, 1 H NMR, and 13 C NMR spectra and products of the alkine hydrolysis of the obtained polymer strongly suggested an alternating copolymer structure consisting of two successive units derived from 1b and 2. The unit from 1b was a linear diester, probably formed by a successive double ring-opening polymerization with isomerization. The 1:1 copolymer composition was not changed by varying the monomer feed ratio in the range between 20:80 and 80:20
