摘要

One novel hydroxyl-terminated block copolyether(PTHF-PEO-PTHF)was synthesized by tetrahydrofuran cationic ring-opening polymerization and linkage of polytetrahydrofuran with two terminals of polyethylene glycol (PEG), using PEG as macroinitiator, boron-trifuoride ethylether complex (BF₃·OEt₂) as catalyst, and epoxy propane (PO) as assistant ring-opening. The obtained copolyether was characterized by IR and ¹H NMR. Moreover, polyurethane elastomers were prepared with hydroxy terminated polyether (HTPE), and the elastomers have satisfactory mechanical properties, low glass transition temperature(T_g=-69.03°C), and good thermal stability. These can meet the requirements of binder for solid propellant.
