Abstract
A polymer nano-particle composition is provided, wherein the nano-particle includes a poly(alkenylbenzene) core and a surface layer including poly(conjugated diene). The polymer nano-particles are preferably less than about 100 nm in diameter. The nano-particles can be made by a dispersion polymerization process.
