摘　　要：以3,3-二溴氧杂环丁烷(BBMO)、四氢呋喃(THF)和环氧氯丙烷(ECH)为单体,1,4-丁二醇(BDO)为引发剂,三氟化硼乙醚(BF3·OEt2)为催化剂,采用阳离子开环聚合法制备BBMO-THF-ECH无规共聚醚;然后将其进行叠氮化反应,制成含能黏合剂BAMO-THF-GAP(3,3-双叠氮甲基氧杂环丁烷-四氢呋喃-叠氮缩水甘油醚)无规共聚醚。研究结果表明:采用单因素试验法优选出制备无规共聚醚的最佳反应条件是w(BDO)=5%(相对于总单体质量而言)、n(BF3·OEt2)∶n(BDO)=1∶2、聚合时间为24 h、叠氮化反应时间为16 h和叠氮化反应温度为110℃。With 3,3- dibromo oxetane （BBMO） , tetrahydrofuran （THF） and epoxy chloropropane （ECH） as monomers, 1,4-butanediol（BDO） as initiator, boron trifluoride diethyl ether（BF3. OEt2） as catalyst, a BBMO-THF-ECH random eopolyether was synthesized by cationic ring-opening polymerization. Then, an energetic adhesive [BAMO- THF-GAP （3,3-his azide methyl oxygen heteroeyclic butane-THF-azide glycidyl ether） random copolyether] was prepared by azide reaction. The research results showed that the optimal reaction conditions of preparing random copolyether were preferred by single factor experiment method when mass fraction of BDO was 5% in total monomers, molar ratio of n （BF3 · OEt2） ： n （BDO） was 1 ： 2, polymerization time was 24 h, reaction time and temperature of azide reaction were 16 h and 110 ℃ respectively.
