| Abstract: | The molecular weight of polytetramethylene glycol (PTMG) prepared from tetrahydrofu-ran (THF) by using cocatalysts of BF3-etherate and epichlorohydrin (ECH) in the presence of butylene glycol(BG) increased sharply with the polymer conversion, but at yields higher than 80% but could be exactly controlled by the molar ratio of BG to BF3. The polyether obtained possessed around 70 mol% primaly hydrcxyl end-groups and a hydroxyl end-group functionality of two. The content of ECH derived units in each polymer chain containing 18.2 or 33.8THF derived units is around 1.60 or 2.16 respectively. |
