In Situ Preparation of Polymer Nanocomposites Based on Sols of Surface-Modified Detonation Nanodiamonds by Classical and Controlled Radical Polymerization

— The possibility of surface modification of detonation nanodiamonds to give them dispersability in methyl methacrylate is considered. In situ polymer composites are obtained by classical radical polymerization and reversible chain-transfer polymerization based on stable sols of detonation nanodiamonds in a monomer. Evidence that nanodiamonds are dispersed in a polymer matrix up to a size of units of nanometers is given. The effect of detonation nanodiamonds on the molecular weight characteristics and glass transition temperature of poly(methyl metacrylate) obtained in their presence is studied.
