Abstract:

The goal of this project is to prepare a series of substituted methylene oxides containing
perfluoroether compounds. The fluids prepared are intended to model high-molecular-weight
perfluoropolyethers which will have similar structural features. The model compounds
will be prepared using newly developed direct fluorination techniques which convert
hydrocarbons of appropriate structure directly to perfluorocarbons. The perfluoroethers
produced will be used in surface studies as well as in aggressive environments where
their comparative stabilities will be measured. Upon identifying structures with
exceptional properties, perfluoropolyether fluids and elastomers based on those structures
will be developed. All of the polymers modeled by the proposed structures are accessible
using our technology and each is expected to give fluid with low pour points and
high oxidative stabilities as well as oxidatively stable elastomers with very low
glass-transition temperatures (-60 to -90 C).
