In order to clarify the differences of polymerizability among 1, 2: 5, 6-dianhydrohexitols, characteristics of the polymerizations of 1, 2: 5, 6-dianhydro-3, 4-di-O-methyl-D-mannitol (1), -L-iditol (2), and-D-glucitol (3) with potassium tert-butoxide (t-BuOK) were compared. The apparent rate constant of polymerization decreased in the order of 1>3>2. The polymerizations of 2 and 3 showed that chain transfer reactions occurred concurrently. End-functionalization in the polymerization of 1 proceeded in a high efficiency over 95% to yield macromonomers having a styryl group or oxetanyl group at a terminal. The result indicated that the polymerization of 1 proceeded in a living manner. The initiator efficiency in the polymerization of 1 was low (0.55) owing to the poor solubility of t-BuOK. 18-Crown-6 ether (18C6) increased the solubility of t-BuOK by forming a complex. The polymerization of 1 in the presence of 18C6 yielded the polymer with a number-average degree of polymerization (DPn) corresponding to the feed molar ratio of the monomer to the initiator ([M] 0/ [I] 0).
