| Abstract: | The reaction of poly amide - 66 (PA66) and maleic acid grafted polyethylene (PE - g - MA) occurred during extrusion process was studied by Molau test and ultraspeed centrifugal experiment. It was verified that the molecules were linked with chemical bonds in the modified polymer that could be used as reactive alloy material. The comprehensive tests of the mechanical properties showed that both the tensile strength at break and yield strength met the requirements of engineering plastics, and the Izod and Charpy impact strength in dry and wet state was obviously improved. |
