Copoly(PPO-THF) (oxypropane-tetrahydrofuran) diol and triol were synthesized by cationic copolymerization of PPO-THF in the presence of 1,4-butanediol (BD) or 2,2 -dihydroxymethyl butanol (DHMB). The results of proton nuclear magnetic resonance verified the chemical structure of the obtained diol an
