Claim:
A compound according to the formula: R f 1 [CH(â€”Oâ€”CH (3-m) R f 2 m )(â€”Oâ€”CF 2 â€”CFHâ€”R f 3 )] n [I] wherein n is 1 or 2, wherein m is 1, 2 or 3, wherein, when n is 1, R f 1 is selected from the group consisting of highly fluorinated alkyl groups which are linear, branched, cyclic, or a combination thereof, which may optionally be substituted, and which may optionally contain one or more catenated heteroatoms; wherein, when n is 2, R f 1 is selected from the group consisting of highly fluorinated alkylene groups which are linear, branched, cyclic, or a combination thereof, which may optionally be substituted, and which may optionally contain one or more catenated heteroatoms; wherein each R f 2 is independently selected from the group consisting of alkyl groups which are linear, branched, cyclic, or a combination thereof, which may optionally be substituted, and which may optionally contain one or more catenated heteroatoms; wherein at least one R f 2 is highly fluorinated; wherein each R f 3 is independently selected from the group consisting of fluorine and highly fluorinated alkyl groups which are linear, branched, cyclic, or a combination thereof, which may optionally be substituted, and which may optionally contain one or more catenated heteroatoms.
