Graft polymer to which combined nitrogen molecules are grafted

摘要

The present invention relates to a modified polymer obtained by grafting of a compound comprising at least one group Q and at least one group A, bonded together by at least, and preferably, one “spacer” group Sp in which:
Q comprises a dipole containing at least, and preferably, one nitrogen atom, capable of being grafted onto the polymer chain by [1,3]-dipolar cycloaddition,A comprises an associative group comprising at least one nitrogen atom,Sp is an atom or a group of atoms forming a bond between Q and A.

1. A modified polymer obtained by grafting of a compound comprising at least one group Q and at least one group A, bonded together by at least, one “spacer” group Sp in which:
Q comprises a comprises a nitrile oxide, nitrone or nitrile imine functional group, A comprises an associative group comprising at least one nitrogen atom, and corresponds to one of the following formulae (II), (III), (IV), (V), or (VI):where:
R denotes a hydrocarbon group which may optionally contain heteroatoms, X denotes an oxygen or sulphur atom or a group —NH Sp is an atom or a group of atoms forming a bond between Q and A.
