Nanoparticles of functionalised, cross-linked vinyl polymer, usable as reinforcing filler in a polymeric matrix. The vinyl polymer is a copolymer of at least the following monomers, which are all copolymerisable by free-radical polymerisation: a non-aromatic vinyl monomer“A”; a monomer“B”bearing a function Z of formula≡Si—X, where X represents a hydroxyl or hydrolysable group; and a cross-linking monomer“C”which is at least bifunctional from the point of view of the polymerisation. The vinyl polymer is preferably a polymethacrylate, in particular a copolymer of methyl methacrylate (monomer A), trimethoxysilylpropyl methacrylate (monomer B) and ethylene glycol dimethacrylate (monomer C), being in the form of nanobeads the diameter of which is of between 10 and 100 nm. |
