Title:
(PER)FLUOROPOLYETHER POLYMERS
Document Type and Number:
WIPO Patent Application WO/2018/108864
Kind Code:
A1
Abstract:
The present invention relates to a novel process for the synthesis of (per)fluoropolyether polymers and to certain novel (per)fluoropolyether polymers. The present invention also relates to the use the (per)fluoropolyether polymers thus obtained, as intermediate compounds for the manufacture of further polymers suitable for use as lubricants, notably for magnetic recording media (MRM).
