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(Tg=-69.03°C), and good thermal stability. These can meet the requirements of binder for solid propellant.
