Fecha de publicación: 22/08/2024 Fuente: WIPO "circular economy" A method for obtaining diallyldialkylammonium halide includes the reaction between allyl halide and a dialkylamine. At least one of the two is at least partially renewable and non-fossil. The diallyldialkylammonium halide can be used as a bio-sourced diallyldialkylammonium halide monomer to produce a bio-sourced polymer incorporating at least the monomer. The polymer can be used in various technical fields.
