Abstract
The α,ω-dialkoxyfluoropolyethers (DA-FPEs) characterizedby structure RHO(CF2CF2O)n(CF2O)mRH have beenrecently developed as a new class of environmentalfriendly hydrofluoropolyethers (HFPEs) suitable as solvents,refrigerants and heat transfer.The synthetic methodologies for the preparation of this newclass of fluid have been reviewed and physical propertiesof selected α,ω-dimethoxyfluoropolyethers havebeen evaluated and compared with analogous hydrofluoropolyethers(H-FPEs) having -OCF2H as end-groups.Atmospheric implications and global warming potentials(GWP) of selected α,ω-dimethoxyfluoropolyethers havebeen also considered.
