| Abstract: | A new process was proposed and studied by mechano chemistry in stirred mill to graft titanium dioxide with polystyrene in solid phase. The better technology factors and results were obtained, and the better applying foreground was proved. The modification mechanisms were analyzed qualitatively, and radical polymerization reaction was thought primarily in the course of modification. |
