Abstract: The invention provides a halogen-containing polyether comprising repeating units of the formula: -(CH2CF2CF2O)a-(CHClCF2CF2O)b-(CC12CF2CF2O)c- (CHFCF2CF2O)d-(CFClCF2CF20)e-(CF2CF2CF2O)f- (I) wherein a, b, c, d, e and f are each an integer of not less than 0 and satisfy the following equations: 2 ?a+b+c+d+e-tf ? 200 and 1 ? a+c-td+f The polyether may be prepared by ring-opening polymer- izing 2,2,3,3-tetrafluorooxetane in the presence of a polymerization initiator to give a polyether comprising repeating units of the formula: -(CH2CF2CF2O)a- (II) wherein a is the same as defined above, and optionally fluorinating and/or chlorinating the polyether (II). The resulting polymers are useful as intermediates in the production of various fluorine-containing compounds, as surfactants, as heat transfer mediums, lubricants, plasticizers, modifiers, etc. and as molding materials.
