Abstract
Process for modifying a polymer comprising the steps of (a) mixing the polymer with a maleimide-functionalized mono-azide and/or a citraconimide-functionalized mono-azide at a temperature in the range 80-250° C. to form a functionalized polymer, and (b) reacting the functionalized polymer with a substance containing one or more functional groups that can react with a maleimide or citraconimide functional group.
