Abstract
Nanoparticles of a functionalized and crosslinked polyvinylaromatic (PVAr) that may be used as reinforcing filler in a polymeric composition, the PVAr being a copolymer of at least: a vinylaromatic comonomer 'A'; a comonomer 'B' carrying a functional group denoted by Z of formula .ident.Si--X, X representing a hydroxyl or hydrolyzable group; a crosslinking comonomer 'C' which is at least bifunctional and polymerizable by means of an addition reaction, it being possible for comonomer C to be vinylaromatic, in this case identical or different to comonomer A or non-vinylaromatic.The PVAr comprises, for example, a copolymer of styrene, ethylvinylbenzene, divinylbenzene and trimethoxysilylpropyl(meth)acrylate, being in the form of nanobeads, the diameter of which is between 10 and 100 nm. This PVAr filler, thanks to a very low density, allows the weight of polymeric compositions, especially elastomer compositions, to be reduced without degrading the reinforcement, and with an notable reduction in hysteresis.
