| In this dissertation we investigate the comparison between a modular intermeshing co-rotating twin screw extruder and counter-rotating twin screw extruder using three different reactive extrusions. These are; (i) thermal cracking of polypropylene due to elevated temperature; (ii) peroxide induced degradation of polypropylene and (iii) maleation of polypropylene with increasing levels of complexity. We consider the variables of screw configurations and screw speeds. Associated with this we carry out non-isothermal, non-Newtonian mathematical modeling of reactions in a modular intermeshing co-rotating twin screw extruder. This simulation includes both screw elements and kneading disc blocks in a composite modular intermeshing co-rotating twin screw extruder. |
