Process for preparing controlled molecular weight perfluoropolyethers
having perfluoroalkyl or perfluorochloroalkyl end groups
摘要:
This invention relates to preparing perfluoropolyethers having neutral end groups by a process based on the photooxidation of C.sub.3 F.sub.6 and/or C.sub.2 F.sub.4, thereby obtaining controlled molecular weight products having perfluoroalkyl or perfluorochloroalkyl neutral end groups, with high yields of useful products.
