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.

Key words: Hydroxy-terminated polybutadiene, Liquid rubber, Block polymer
