Propylene copolymerized with N-allyl-N,N-bis(trimethylsilyl)amine in the rac-Me2Si[2-Me-4-ph(Ind)2]ZrCl2/MAO catalyst system to yield side-chain functionalized PP-g-NH21~2. The molar ratio with comonomer can be controlled by using different catalyst concentration, temperature and amount of MAO. The copolymer PP-g-NH2 can use as the compatibilizer to prepare PP/PP-g-NH2/clay nanocomposites. It is because the amino group on the polymer side chain can provide reactive sites to exchange with the cations (Li+, Na+, etc.) which located between the clay interlayers3~4. All the products are characterized by 1H NMR, FT-IR, DSC, TGA and XRD.
