Properties of high cis-1,4 content hydroxyl-terminated polybutadiene and its application in composite solid propellants

Defence Technology
In this paper, high cis-1,4 content hydroxyl-terminated polybutadiene (cis-HTPB) with different molecular weights was prepared through the oxidative cracking process using cis-butadiene rubber as raw material. Firstly, this article comprehensively compared the differences between cis-HTPB and conventional I-HTPB in terms of molecular weight ...
