Abstract
Method for polymerisation over nanoparticles wherein the polymer grows over said nanoparticles, which are initially provided in virgin state and contain the absorbed water characteristic of each nanoparticle, are heat-treated at a temperature of between 50 and 500° C. for less than 24 hours such that OH groups are released on the surface of said nanoparticles, introducing same in a polymerisation reactor with a monomer to which a catalyst is added, and the polymerisation is carried out in a liquid medium according to a linear temperature increase, as well as a polymer charged with the nanoparticles thus obtained.
