Abstract (en)
[origin: WO2022034274A1] The invention relates to a process for chemically modifying a polymeric part in order to provide it with flame retardancy properties or to enhance said properties, said process comprising a step of reacting at least one polymeric part comprising at least one polymer of which the reactive groups comprise amine groups and/or hydroxyl groups with a flame retardant compound comprising at least one group that reacts, by nucleophilic substitution or nucleophilic addition, with some or all of the amine groups and/or hydroxyl groups of the polymer or polymers, the reaction being carried out with said compound in gaseous form.
