the main objective of the present work was to synthesis polyamide 6 through anionic polymerization of ε-caprolactam in an internal mixer. the reaction time and the rheological properties of samples during the polymerization were studied. the samples were characterized by thermo gravimetry analysis (tga), differential scanning calorimeter (dsc) and ft-ir spectrometer. the melt flow behavior and ...

The concept of anionic polymerization was first developed by Ziegler and Schlenk in early 1910. Their pioneering work on the polymerization of diene initiated with sodium metal set the stage for the use of alkali metal containing aromatic hydrocarbon complexes as initiators for various α-olefins. In 1939, Scott and coworkers used for the first time the alkali metal complexes of aromatic hydroca...

Anionic polymerization is an established process for the synthesis of well-defined block copolymers. Due to high reaction rates, a good knowledge and its heat generation great importance safe control. This be achieved by development validation combined kinetic transport model. The model was based on experimentally anionic homo-polymerization styrene that expanded co-polymerization isoprene carr...
