【Abstract】 A novel graft macromolecular coupling agent with well-defined structure was synthesized by atom transfer radical polymerization(ATRP). Since the silicon of graft polymers possesses a strong affinity to hydroxyl mineral, it gives fillers some new properties such as the increase of the interaction of fillers with matrix. The properties, structure of macromolecular coupling agent and its composite were studied by dynamic mechanical spectra, IR, UV, NMR, GPC and SEM.更多还原
