摘　　要：新一代高能固体推进剂粘合剂除自身必须具有能量外，同时还要求具备与硝酸酯的混溶能力要强（Ｐｌ／Ｐｏ＞２），玻璃化温度要低（Ｔｇ＜－５４℃）等特点．本文作者曾将叠氮基引入聚合物侧链而赋予其能量特征［１］，观察到３，３双（叠氮甲基）环氧丁烷（ＢＡＭＯ）与...The energetic copolyether of 3,3\|bis(azidomethyl)oxetane(BAMO) and 3\|nitrato\|methyl\|3\|methyloxetane(NMMO) was synthesized by using BF\-3 Et\-2O and 1,4\|butanediol as an initiator system for the cationic ring\|opening polymerization, with which the molecular weight could be controlled. The copolymer structure was characterized with FT\|IR,1H\|NMR and 13C\|NMR. The arrangement of the monomer units in the copolyether chain is almost the ideal system. The DMA results indicated that the miscibility between the copolyether and nitrate ester plasticizer is excellent. This copolyether could be applied for solid propellant binder.\=
