Abstract:Hydroxyl-terminated polybutadiene (HTPB) was prepared by anionic polymerization using cyclohexane as solvent, and YB was used as dissociation reagent in the synthesis of HTPB. The sequent influence on the molecular distribution, average functionality and the polymerization temperature and pressure in the reactor were investigated in detail. Finally,by using YB, HTPB could be controlled, of which the molecular weight distribution was smaller than 1.3 and the average functionality was improved.
Keywords:hydroxyl-terminated polybutadiene (HTPB)  dissociation reagent  average functionality
