Buch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Polyamide 6 is one of the most important engineering plastics and is widely used in demanding technical and food-contact applications. However, its thermal performance can be limited in applications requiring high heat-deflection resistance.Radiation crosslinking can significantly improve the thermal and thermomechanical properties of PA6. However, conventional crosslinking enhancers such as triallyl isocyanurate are volatile, toxicologically problematic, and not approved for food-contact applications in Europe.This work presents the development and evaluation of new biogenic and semi-biogenic crosslinking enhancers for the radiation crosslinking of PA6. Special emphasis is placed on allylamide-based additi ves, their synthesis, thermal stability, crosslinking efficiency, migration behaviour, and toxicological assessment in the context of European food-contact regulation. The results show that selected allylamides can effectively crosslink PA6 under electron-beam irradiation and improve heat-defl ection performance. Promising materials were further evaluated by genotoxicity and migration studies to assess their potential for future food-contact applications.The study therefore connects polymer chemistry, material performance, toxicological evaluation, and European food-contact regulation.…
