The invention relates to polymeric-inorganic nanoparticle compositions and preparation processes thereof. The invention also relates to an additive and lubricant compositions comprising these polymeric-inorganic nanoparticle compositions, as well as to the use of these polymeric-inorganic nanoparticle compositions in an oil lubricant formulation to improve tribological performance, in particular to improve extreme pressure performance and friction reduction on metal parts. L'invention concerne des compositions nanoparticulaires polymères inorganiques et leurs procédés de préparation. L'invention concerne également un additif et des compositions lubrifiantes comprenant ces compositions nanoparticulaires polymères inorganiques, ainsi que l'utilisation de ces compositions nanoparticulaires polymères inorganiques dans une formulation de lubrifiant huileux pour améliorer les performances tribologiques, en particulier pour améliorer les performances de pression extrême et la réduction de frottement sur des pièces métalliques.
