Abstract: This work developed the cationic ring opening polymerization of 3-methyl-3-hydroxymethyleneoxetane initiated by BF3·OEt2directly. The resulted polymer was easily dissolved in polar solvents such as CH3OH, C2H5OH, DMSO and N-methyl pyrrolidone, but not dissolved in water, tetrahydrofuran and other non-polar solvents. The TGA study of sample 1 indicates that the polymer starts to pyrolyze at 360 ℃. There is a melting endotherm at 125.9 ℃ in the DSCcurve of sample 1, and the melting peak enlarged with decreasing the amount of catalyst added, which means that sample 1 is essentially linear, and with increasing the amount of catalyst the resulted polymer becomes slightly branched.

Key words: 3-Methyl-3-hydroxymethyleneoxetane, Ring-opening polymerization, Characterization
