Microwave Assisted Synthesis and Characterization of Glycidyl Azide Polymers Containing Different Initiating Diol Units

Glycidyl azide polymers (GAPs), containing different initiating diol units were prepared by treating the corresponding poly(epichlorohydrins) (PECHs) with sodium azide under microwave irradiation (600 W power) at 80 °C, during 12 min. The PECHs containing different diol units were synthesized by the polymerization of epichlorohydrin using borontrifluoride etherate as initiator in the presence of small amounts of low molecular weight diols. The synthesized PECHs and GAPs, containing different initiating diol units, were characterized by various spectroscopic techniques and by thermal analysis (DSC). These results are reported and discussed.
