Problems solved by technology

[0006] However, when the amino group is directly attached to the PFPE chain, the amino group has poor basic properties
As a result, the resulting PFPE-amino derivatives are poorly reactive and of little use both as intermediates for the synthesis of polymers and as additives (e.g. in coating compositions)
[0007] Furthermore, the syntheses known in the art are inconvenient on an industrial scale because they require several steps of chain-end modification under intricate and expensive reaction conditions

[0265] Example 5 - Synthesis of Polymer (P-D2) Comprising Zwitterionic Groups

[0266] A four-necked round-bottomed flask equipped with a mechanical stirrer, a condenser and a thermometer was charged with 18.6 g of a PFPE-aminopolymer (MW=2925; 6.36 mmol) obtained according to the procedure disclosed in Example 4, 2.3 g of Sodium chloroacetate (MW=116; 20 mmol), 20 g of ethanol and 1.0 ml of water.

[0267] The temperature was raised to 80 °C and the reaction was left under stirring for 8 hours. After cooling at room temperature, 20 g of HFX, 20 ml of water and 10 g of isobutanol were added to the reaction mixture until separation of the organic and aqueous phases was observed. The lower organic phase was recovered and the solvent was evaporated in vacuo, leaving 19.2 g of product as a residue.

[0268] pass 1 H-NMR and 19 Characterization by F-NMR confirmed the following structure:

Abstract

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

Description

[0001] Cross References to Related Applications [0002] This application claims priority from European Application No. 14193944.7 filed on November 19, 2014, the entire content of which is hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to amino derivatives of perfluoropolyether polymers, their production methods and uses. Background technique [0004] From an industrial point of view, perfluoropolyether (PFPE) polymers containing amino groups at their chain ends (hereinafter "PFPE-amino") are potentially interesting materials. [0005] PFPE-amino and methods for their production are known in the art. For example US 6,083,600 (INTERNATIONAL BUSINESS MACHINES CORPORATION) discloses PFPE in which the polymer backbone is terminated by at least one amine end group which is connected to the polymer via a methylene bridging group main chain connection. US 6,984,759 (SOLVAY SOLEXIS S.P.A.) discloses a process for the pre...
