Cationic ring-opening polymerization behavior of a seven-membered cyclic sulfite ( 1) was examined. 1 was prepared by the reaction of 1,4-butanediol with SOCl 2 in 58% yield. The cationic polymerization of 1 was carried out at 0, 25, 60, or 100ะŠC with trifluoromethanesulfonic acid (TfOH), methyl tri

Anionic ring-opening polymerization of a seven-membered cyclic carbonate, 1,3-dioxepan-2-one ( 1), was carried out to observe that the higher the polymerization temperature and lower the initial monomer concentration were, the lower the yield and molecular weight, and wider the molecular weight dist

The cationic ring-opening polymerization of six-membered cyclic pseudoureas, 2-(1-pyrrolidinyl)-( 2a) and 2-morpholino-5,6-dihydro-4H-1,3-oxazine ( 2b), was examined, which proceeded in two different ways, depending on the nature of initiator.

Cationic copolymerization of seven-membered cyclic sulfite, 1,3,2-dioxathiepane-2-oxide ( 1) and oxetane ( 2) in one-shot feeding was carried out to obtain the corresponding copolymer. When a mixture of equimolar amount of 1 and 2 reacted at 0ะŠC in the presence of methyl trifluoromethanesulfonate (T
