Abstract:
1. A process for producing a particulate nanocomposite material which comprises particles that comprise a) at least one inorganic or organo(semi)metallic phase which comprises at least one (semi)metal M; and b) at least one organic polymer phase; said process comprising polymerizing at least one monomer MM which comprises: at least one first cationically polymerizable monomer unit A which has a metal or semimetal M, and at least one second cationically polymerizable organic monomer unit B which is joined to the polymerizable unit A via one or more covalent chemical bonds, under cationic polymerization conditions under which both the polymerizable monomer unit A and the polymerizable organic monomer unit B polymerize with breakage of the bond between A and B, wherein the polymerization is performed in an aprotic solvent in which the nanocomposite material is insoluble, in the presence of at least one polymerization initiator and of at least one further substance selected from α) at least one surface-active substance and β) at least one particulate material, or wherein the polymerization is performed in an aprotic solvent in which the nanocomposite material is insoluble, in the presence of at least one polymerization initiator, or the polymerization product is treated in the presence of at least one surface-active substance with a solution of a base in a protic solvent.
