Grafting of Hexafluoropropylene onto Polytetramethylene Glycol by Radical Reaction

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.
