Abstract
A method for performing a one-pot synthesis of a blend of nanoparticles and liquid polymer includes polymerizing a first monomer and optionally a second monomer in a hydrocarbon solvent to form the liquid polymer. The polymerization is terminated before completion with a quenching agent. Then a charge of polymerization initiator, and a mixture of cross-linking agent and mono-vinyl aromatic monomer are added. This causes further polymerization whereby nanoparticles are formed having a core including the cross-linking agent, and a shell including the first monomer or the first monomer and the second monomer. Nanoparticle/liquid polymer blends resulting from the method and rubber compositions incorporating the blends are also disclosed.
