An aqueous dispersion includes an aqueous medium and self-crosslinkable core-shell particles dispersed in the aqueous medium. The core-shell particles include (1) a polymeric core at least partially encapsulated by (2) a polymeric shell having urethane linkages, keto and/or aldo functional groups, and hydrazide functional groups. Further, the polymeric core is covalently bonded to at least a portion of the polymeric shell.

The present invention relates to an optical film and method of manufacturing the same. The optical film of the present invention includes an acrylic resin and a core-shell type graft copolymer wherein the core includes a conjugate diene rubber, and the shell includes an acrylic monomer, an aromatic vinyl monomer, and a maleimide monomer.

A method is provided for synthesizing a core-shell nanoparticle that includes the following steps: providing a polymeric seed (in a solvent) that includes mono-vinyl monomer cross-liniked with a cross-linking agent to form the core of the nanoparticle, the core has an average diameter of from about nanometers to about 10,000 nanometers, and the core has polymer chains with living ends; adding a stabilizer to stabilize the seed and prevent the seed from precipitating out of solution; and grafting a shell species onto the living ends of the core to form the shell of the nanoparticle. A core-first synthesized nanoparticle, along with a rubber composition and tire product are also provided.
