Abstract
The invention relates to a process which comprises the reaction of a (per)fluoropolyether peroxide with an optionally substituted aromatic or heteroaromatic compound. The process allows to obtain (per)fluoropolyether compounds having two chain ends, wherein one or both chain ends is a —CF2— group covalently bound to an optionally substituted aromatic or heteroaromatic group through a -carbon-carbon- bond. The invention further relates to the use of these compounds and to their derivatives as additives for perfluorinated oils and greases.
