Research Abstract

A facile synthetic method for graft copolymers with controllable molecular weight was established via combination of polyaddition and conventional free radical polymerization. Nano-wires containing metal salts were successfully synthesized via the addition of metal salts to the C=S moieties in the stem chains of the graft copolymers. Reducing the metal salt yielded nano-wires containing 0-valent metals. In addition, highly refractive nano-particles were developed by applying this method to nano-particle synthesis.
