The cationic polymerization of 3,3-bis(azidomethyl)oxetane (BAMO) was compared with the polymerization of 3,3-bis(chloromethyl)oxetane (BCMO). The initiating system, boron trifluoride diethyl etherate/diethylene glycol (system. name: 22'-oxydiethanol) was used and it was shown that unusually high concentrations were necessary to observe polymerization. NMR analysis of poly(BAMO), produced by this initiating system, suggested that BAMO polymerization proceeds through the activated-monomer mechanism. The oligomer functionality, which was found close to 2, supports this suggestion. It was also shown that by copolymerization of BAMO with 3-chloromethyl-3-(2,5,8-trioxadecyl)oxetane the crystallization tendancy and the glass transition temperature of poly(BAM0) decreased. 0 1991, Huthig & Wepf Verlag, Basel CCC 0025-1 16X/91/$03.00
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
