CH3COBF4催化四氢呋喃聚合的研究
A Study of Polymerization of THF with CH3COBF4 as Catalyst
【摘要】 本文介绍了CH3COBF4催化四氢呋喃（THF）的聚合方法,讨论了THF的聚合反应机理和动力学行为。经计算表观活化能为71.68kJ/mol,0℃、6℃和15℃时的表现聚合速度常数分别为1.18、2.35和6.07×10-3L·mol/s;说明反应温度对聚合速度常数有明显的影响.
【Abstract】 In this paper,a synthetic method of PTHF was introduced with CH3COBF4 as catalyst and the mechanism and kinetic behaviour of polymerization of THF were discussed in detail.The polymerization temperature has a great influence on the polymerization rate constants.The apparent rate constants of polymerization are 1.18,2.35 and 6.07×10-3 L·mol-1·s-1 respectively at 0,6 and 15℃ and the apparent active energy is 71.68 kJ/mol.
