| Abstract: | Unsaturated double bonds were introduced onto the surface of Al 2 O 3 particles by surface treatment with a coupling agent KH570. Then, the treated Al 2 O 3 particles were further encapsulated by PMMA by method of surface grafting polymerization of MMA on the surface of Al 2 O 3 particles in solution polymerization. The surface structures after these surface treatments were studied with IR and XPS. The results indicated the surface of Al 2 O 3 particles was grafted with KH570 and PMMA. At the same time, we obtained composites of PP/ Al 2 O 3 and studied the mechanical properties. |
