ABSTRACT:
Copolymers containing oxymethylene and 2-fluoromethoxyethylene repeat units. These copolymers, of improved heat stability, may be prepared by copolymerizing trioxane with a derivative of a cyclic ether whose molecule contains at least two adjacent carbon atoms and in which an oxymethylene group carries a fluoromethyl substituent, especially epifluorohydrin.
