실험 절차

Polymerization of THF was carried out according to the same procedure as in Example 1 except that phosphotungstic acid was used as a catalyst solution of a specific gravity of 2.05 and the reaction liquid volume V in the reactor 1 was kept constant at 420 ml. First, in order to find the relation between Mw/Mn and V/F, with P/V fixed at 1.9 kW/m3, the Mn and the Mw/Mn of PTMG obtained under conditions 1 to 3 shown in Table 1 were measured. The results obtained are shown in Table 1.
