3,3'-Bisbromomethyl oxetane-3-bromomethyl-3'-methyl oxetane (BBMO-BrMMO) random copolymer was synthesized by cationic ring opening polymerization using 1,4-butanediol/boron trifluoride etherate initiator system. 3,3'-Bisazidomethyl oxetane-3-azidomethyl-3'-methyl oxetane (BAMO-AMMO) random copolymer was then synthesized through microwave synthesis. Azidation kinetic analysis was carried out at the same time. The results indicate that composition and micro-sequential distribution of BBMO-BrMMO random copolymers are controllable through regulating molar feed ratio of monomers. Reaction rate of azidation is controlled by the amount of tetrabutyl ammonium bromide (TBAB), k=48.85 L/(mol·h) (TBAB=1%); k=51.95 L/(mol·h) (TBAB=5%); k=62.72 L/(mol·h) (TBAB=10%). Reaction time of azidation is shortened by microwave synthesis, the security of the reaction process is improved accordingly, and microwave synthesis does not change the chain structure of copolymers.

Key words: cationic ring opening polymerization, azidation kinetics, microwave synthesis
