Title (EN) CORE-FIRST NANOPARTICLE FORMATION PROCESS, NANOPARTICLE, AND COMPOSITION
(FR) PROCÉDÉ DE FORMATION DE NANOPARTICULES EN COMMENÇANT PAR LE CŒUR, NANOPARTICULE ET COMPOSITION
Abstract:
(EN) A method is provided for synthesizing a core-shell nanoparticle that includes the following steps: providing a polymeric seed (in a solvent) that includes a mono-vinyl monomer cross- linked with a cross-linking agent to form the core of the nanoparticle, the core has an average diameter of from about nanometers to about 10,000 nanometers, and the core has polymer chains with living ends; adding a stabilizer to stabilize the seed and prevent the seed from precipitating out of solution; and grafting a shell species onto the living ends of the core to form the shell of the nanoparticle. A core-first synthesized nanoparticle, along with a rubber composition and tire product are also provided.
(FR) L'invention concerne un procédé de synthèse de nanoparticules à cœur-coquille comprenant les étapes suivantes : l'obtention d'une amorce polymère (dans un solvant) qui inclut un monomère monovinylique réticulé avec un agent de réticulation pour former le cœur de la nanoparticule, le cœur ayant un diamètre moyen d'environ quelques nanomètres à environ 10 000 nanomètres et le cœur contient des chaînes polymères ayant des extrémités vivantes ; l'ajout d'un stabilisateur pour stabiliser l'amorce et empêcher la précipitation de l'amorce dans la solution ; et le greffage d'une espèce pour coquille sur les extrémités vivantes du cœur pour former la coquille de la nanoparticule. Une nanoparticule synthétisée en commençant par le cœur, une composition de caoutchouc et un produit de pneumatique sont également décrits.
