| In this dissertation we investigate the continuous polymerization of caprolactam and fabrication of polyamide 6 and their blending in a modular intermeshing co-rotating twin screw extruder using an anionic initiator system. We consider the variables of screw configuration, temperature profiles, screw speed and throughput on the extent of reaction, polymer molecular weight and mechanical properties. Associated with this we carry out non-isothermal, non-Newtonian mathematical modeling of reacting caprolactam in a modular intermeshing twin screw extruder. This simulation includes both screw elements and kneading disc blocks in a composite modular intermeshing co-rotating twin screw extruder. We further investigate the continuous drawing down and melt spinning of polyamide 6 filaments and their blends subsequent to their melt spinning. |
