Chemical and Morpholigical Evolution of PA-6/Epm/Epm-g-MA Blends in a Twin Screw Extruder

摘要

Chemical conversion and morpholigical evolution of PA-6/EPM/EPM-g-MA-blends along a twin screw extruder were monitored by quickly collecting small samples from the melt as specific barrel locations. The results show that the MA content of all blends decreases drastically in the first zone of the extruder, i.e., upon melting of the blend components. Significant changes in morpholigy are also observed at this stage. A correlation between chemistry and morpholigy could thus be established.
