Abstract
2-[(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyloxy)methyl]oxirane(3) was prepared by the nucleophilic substitution reaction of epichlorohydrin(1) with 1,1,2,2-tetrahydroperfluoro-1-octanol(2).Poly{2-[(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyloxy)methyl]oxirane}(4) was synthesized by ring-opening polymerization of 3 using boron trifluoride etherate as the initiator.The structures were characterized by 1H NMR and IR.The optimal reaction conditions for synthesizing of 3 were as follows:2 was 65 mmol,n(1):n(2) was 3:2,reaction temperature was 70 ℃ and reaction time was 18 h.The molecular weight of 4 was 1 400 when n(3):n(BF3·Et2O) was 25:1 in the process of ring-opening polymerization.
