摘要
以1,4-丁二醇为引发剂,以三氟化硼乙醚络合物为催化剂,以3-叠氮甲基-3-甲基氧丁环(AMMO)为单体,以CH2Cl2为溶剂,按阳离子开环聚合机理,合成了含能粘合剂3-叠氮甲基-3-甲基氧丁环均聚物(PAMMO)。重点研究了催化剂用量对聚合反应的影响,结果表明,降低催化剂用量有利于实现可控聚合。采用DCS、TGA、IR等手段研究了PAMMO的结构和性能。PAMMO的玻璃化转变温度为-40.37℃。
Using butanediol as initiator, boron-trifluoride etherate as catalyst, 3-azidomethyl-3-methyloxetane homopolymer （PAMMO） was synthesized by the cationic polymerization of 3-azidomethyl-3-methyloxetane（AMMO） which was carded out in dichlorometane. The effect of catalyst concentration on polymerization was studied by experiment. The structure and properties of PAMMO were also characterized by DSC, TGA and IR measurements. The results show that the polymerization can be controlled by decreasing catalyst＇s concentration . The glass transition temperature（Ts） of PAMMO was 40.3 ℃. PAMMO can be used as the liquid energetic binder of cast propellant and the soft segment of energetic thermoplastic elastomer.
