摘要
四氢呋喃共聚型GAP粘合剂的合成分两个步骤：a．通过四氢呋喃（THF）和环氧氯丙烷（ECH）在BF3·加二元醇催化下的阳离子开环聚合反应合成端羟基THF－ECH共聚醚；b．端羟基THF－ECH共聚醚叠氮化生成THF共聚型GAP粘合剂。THF共聚型GAP常温和低温力学性能明显优于均聚GAP，感度比均聚GAP低，热稳定性和均聚GAP相当。但是，均聚GAP和硝酸酯的相容性明显高于THF共聚型GAP。
The synthesis of tetrahydrofuran copolymerized GAP binder includes two steps: THF and ECH (epichlorohydrin) are copolymerized with the help of catalyst(BF3·+diol) through cation ring opening copolymerization to hydroxyl terminated THF-ECH copolyethers; THF copolymerized GAP is synthesised by the azidation of hydroxyl THF-ECH copoyethers. Compared with homopolymer GAP, THF copolymer GAP has more excellent mechanical performances and less sensitivity, and possesses the same degree of thermal stability. However, homopolymer OAP is more solvophilic in high energetic nitratca ester plasticser than THF copolymerised GAP.
