【Abstract】 s: The homopolymers with higher viscosity of 1,2-epihydrin were synthesized by the catalyst of BF 3·Et 2O. Influences of different reaction parameters on the viscosity were tested. The esterified polyethers synthesized by different catalysts were also studied. The results indicated that properties of esterified polyethers synthesized from tungstosilicic acid were better than those of esterified polyether synthesized from p-toluenesulfonic acid?更多还原
