| Abstract The surface oxdation of polyolefine by KMnO4/H2SO4,K2Cr2O7/H2SO4 or (NH4)2S2O8 solution or catalysts FeCl3 or CuSO4 has been studied.The structure of the product was characterized by IR and XPS spectra and melting point test.It is found that the preferred reaction condition is about 4560 and 45min. C content in the oxidation systems of polyethylene decreased from that of 80804% to 31907%,69 905% and 78669% by the catalysts of KMnO4/H2SO4/FeCl3/CuSO4, K2Cr2O7/H2SO4/FeCl3 and K2Cr2O7/H2SO4/CuSO4 respectively.The Cl content in all the oxidized sample increased by FeCl3 catalysis,This revealed that the chloration maybe took place. For K2Cr2O7/H2SO4/FeCl3 oxidation system the O content in the oxidized sample increased much more. |
