Title:
(PER)FLUOROPOLYETHERS WITH bi- OR ter-PHENYL END GROUPS
Document Type and Number:
WIPO Patent Application WO/2013/120827
Kind Code:
A2
Abstract:
The present invention relates (per)fluoropolyether compounds comprising a (per)fluoropolyether chain (Rf) having at least two chain ends, wherein at least one of said chain ends have a bi- or ter-phenyl group bearing at least one nitro group and, optionally one or more further substituents. The invention also relates to processes for the preparation of such compounds and to their use for the preparation of lubricant compositions in the form of oils or greases.
