GRAFT POLYMER TO WHICH COMBINED NITROGEN MOLECULES ARE GRAFTED

摘要

The present invention relates to a modified polymer obtained by grafting a compound thereto, said compound including at least one group Q and at least one group A bonded together by at least one, and preferably only one, spacer group Sp, where: Q includes an azo-carbonyl group which can be grafted onto the polymer chain by an ene reaction; A includes a combined group including at least one nitrogen atom; and Sp is an atom or a group of atoms forming a bond between Q and A.
