The present invention relates to novel (per)fluoropolyether polymers characterized by high molecular weight and high functionality, to a process for their manufacture and to their use as intermediate compounds in the preparation of further polymers.

(Per)fluoropolyether (PFPE) polymers

The present invention relates to novel (per)fluoropolyether polymers and their use as lubricants, in particular for Magnetic Recording Media (MRM).

(per)fluoropolyether polymers

The present invention relates to (per)fluoropolyether (PFPE) amino derivatives, a method for their manufacturing and their uses.

Amino derivatives of perfluoropolyethers

Hydrogenated fluoromodified polymers obtainable by reaction among hydrogenated polymers and the modifier having a polyether structure:

Modified hydrogenated polymers

Coatings based on perfluoropolyethers terminated with acrylic groups and containing ethoxylic groups as a connecting bridge between the fluorinated part and the (meth)acrylic group.

Coatings based on perfluoropolyethers containing acrylic groups

Coatings obtainable from crosslinkable polyesters resins based on perfluoropolyethers obtainable from hydroxy-terminated PFPE, with acid anhydride and/or a diacid, a polyol with functionality higher than 2 and optionally in mixtures of diols having a functionality of 2, the resins being also even 70% weight/weight soluble in xylene.

Coatings based on polyesters from perfluoropolyethers

The invention relates to two classes of prepolymers containing a perfluoropolyethereal chain and carboxylic end groups, suitable as cross-linking agents for epoxy prepolymers. The first class contains anhydride-derived end groups; the second lactone-derived end groups; prepolymers therefrom are also disclosed. Additional non-fluorinated curing agents may also be added.

Prepolymers containing a perfluoropolyethereal chain and carboxylic end

A class of cross-linked fluorinated polyurethanes, which can be used for protecting and reinforcing coatings on films, sheets, laminates and similar thin structures made of cellulose, graphite, mica, kaolin, leather etc. as well as for adhesive and reinforcing material in multi-layer structures made of films, sheets, laminates and similar thin structures made of graphite, mica, kaolin, etc. These polyurethanes can be obtained starting from the following components:
