The present invention relates to a method of functionalizing a polymer, said functionalizing method comprising treating said polymer with a mono-azide of the formula: at a temperature in the range of 80 < 0 > C to 250 & (I) (II) (III), In this formula, m is 0 or 1, n is 0 or 1, n + m = 1 or 2, X is a linear or branched, aliphatic or aromatic hydrocarbon moiety having 1 to 12 carbon atoms and optionally containing heteroatoms, R b is hydrogen, 1 to 6 carbon atoms and O, S, P , Linear or branched alkyl groups optionally substituted by Si or an N-containing functional group, alkoxy groups having from 1 to 6 carbon atoms, and halogens, R a is each independently selected from the group consisting of hydrogen, May be selected from linear or branched alkyl groups having from one to six carbon atoms or may form a saturated or unsaturated aliphatic or aromatic ring structure with one or more other R < a >. |
