The present invention relates to a modified polymer obtained by grafting 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 an azo-carbonyl group capable of being grafted onto the polymer chain by an “ene reaction”,
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.
本发明涉及一种经过接枝改性的聚合物,该聚合物由至少一个含有Q基团和至少一个A基团的化合物接枝而成,其中Q包括一个偶氮羰基团,能够通过“烯基反应”接枝到聚合物链上,A包括至少一个含有氮原子的关联基团,Sp是一个原子或原子团,形成Q和A之间的化学键。
