Patent ID: 8791254

Claim:
A hydrofluoroether compound represented by one of the following general formulas (I) and (II): wherein each R F is independently a linear or branched perfluoroalkyl group that optionally contains at least one catenated heteroatom and that optionally comprises a terminal moiety selected from —CF 2 H, —CFHCF 3 , and —CF 2 OCH 3 ; each R F ′ is independently a fluorine atom or a perfluoroalkyl group that is linear or branched and that optionally contains at least one catenated heteroatom; Y is a covalent bond, —O—, —CF(R F ′)—, or —N(R F ″)—, wherein R F ″ is a perfluoroalkyl group that is linear or branched and that optionally contains at least one catenated heteroatom; R H is an alkyl or fluoroalkyl group that is linear, branched, cyclic, or a combination thereof and that optionally contains at least one catenated heteroatom; and R H ′ is an alkylene or fluoroalkylene group that is linear, branched, cyclic, or a combination thereof, that has at least two carbon atoms, and that optionally contains at least one catenated heteroatom; and wherein the catenated heteroatom is selected from divalent ether oxygen atoms or trivalent nitrogen atoms.
