FLUORINATED CHITOSAN DERIVATIVES

摘要

A poly-[1-4]-D-glucosamine derivative comprising [1-4]-D-glucosamine recurring units and comprising a fluoropolyether chain bound to the nitrogen atom in the C-2 position of at least one of the [1-4]-D-glucosamine recurring units.

1. A poly-[1-4]-D-glucosamine derivative which comprises at least 0.1 mol % and at most 25 mol % of recurring units of formula (II); at most 10 mol % of recurring units of formula (III); and recurring units of formula (Ia) in an amount complementary to 100 mol %wherein in formulas (Ia), (II) and (III) R is —H or a C1-C20 alkyl group, optionally comprising cyclic or aromatic moieties, optionally comprising heteroatoms in the alkyl chain, and/or optionally comprising functional groups; and wherein in formula (II) FPE indicates a fluoropolyether chain; L indicates a linking group between the fluoropolyether chain and the nitrogen atom in the C-2 position in the D-glucosamine unit and T a terminal group.
