Abstract:
A hexafluoropropene oxide polymer represented by the following general formula (1): ##STR29## wherein R is --COF, --I, --Br, --CH.sub.2 OH, --CH.sub.2 OCH.sub.2 CH.dbd.CH.sub.2, --COOR.sup.1 or --CONR.sup.2 R.sup.3 wherein R.sup.1, R.sup.2 and R.sup.3 are independently hydrogen or monovalent hydrocarbon groups of 1 to 20 carbon atoms which may contain a nitrogen, oxygen, silicon or sulfur atom, R.sup.2 and R.sup.3 may be the same or different, or R.sup.2 and R.sup.3, taken together, form a ring with the nitrogen atom,Rf is a perfluoroalkylene group of 1 to 6 carbon atoms or a perfluorooxyalkylene group of 2 to 10 carbon atoms having an ether bond, which may contain a cyclic structure, andx and y are positive numbers and the sum of x and y is from 30 to 400,said polymer having a dispersity Mw/Mn of up to 1.10, the dispersity being given as a weight average molecular weight (Mw) divided by a number average molecular weight (Mn).
