Abstract
The invention concerns a method for preparing polymers, characterised in that it consists in contacting: at least an ethylenically unsaturated polymer, at least a source of free radicals, and at least a compound of general formula (IA) wherein R2 represents a group formula (I); R3 being advantageously an electron-attracting group.
