【摘要】 端羟基液体丁二烯橡胶（HTPB）的活性端羟基在适当条件下可制备成大分子引发剂，将具有特定功能的聚合物通过嵌段共聚改性的方法连接在HTPB的两端，形成结构多样、功能丰富的嵌段聚合物。本文综述了近年来利用HTPB制备的嵌段聚合物在火箭推进剂性能改进、刺激响应性聚合物、可拉伸半导体材料和两亲性聚合物等方面的研究进展，并对利用HTPB制备新型嵌段聚合物的未来进行了展望。更多还原

【Abstract】 The active hydroxy-terminated liquid polybutadiene rubber(HTPB) can be prepared into a macromolecular initiator under appropriate conditions. The polymers with specific functions are connected to both ends of HTPB by the method of block copolymerization modification to form block polymers with diverse structures and rich functions. In this paper, the recent research progress of HTPB block polymers in improving the performance of rocket propellants, stimulation-responsive polymers, stretchable semiconductor materials and amphiphilic polymers are reviewed. The future of HTPB block polymers is also prospected.更多还原
