摘　　要：A well-defined modification of polytetramethylene glycol （PTMG） was realized by radical grafting with hexafluoropropylene （HFP）. The structure of grafted product was confirmed by means of IR, ^1H NMR and ^13C NMR. The effects of the amount of initiator, reaction time and temperature on the grafting HFP onto PTMG were investigated.A well-defined modification of polytetramethylene glycol （PTMG） was realized by radical grafting with hexafluoropropylene （HFP）.
