| Abstract: | The article deals with reactive extrusion for grafting of Maleic Anhydride (MAH) on Polypropylene (PP) in a single-screw extruder The effects of PP types, added amount of DCP, the ratio of MAH/DCP,and extrusion conditions on grafting ratio and melt viscosity of products were investigated It was found that DCP concentration and the value of MAH/DCP would substantially influence the grafting ratio, which tended to show peak-like changes with increase of both DCP concentration and MAH/DCP; the extent of thermal and oxidative degradation on PP macromolecules during the melt grafting reaction was related with PP types, DCP concentration and extrusion conditions. By selection of suitable extrusion conditions and use of some additives, the degradation of PP could be limited to some extent |
