Anionic copolymerization of nylon 6/12: A comprehensive review

This review aims to provide a concise insight into the rapidly growing anionic ring‐opening copolymerization of nylon 6/12 and its related structures. This study analyzes the relationship between the structures of polymerization components and the relevant properties to achieve optimum copolymerization formulation. Specific emphasis is placed on how the catalyst type and temperature influence the final copolymer structure. The present work reviews available literature about nylon 6/12 synthesis published between 1960 and 2017 and investigates structures linked to polymerization mechanisms behind them. Moreover, experimental results derived from direct/indirect identification methods of structures are presented. The crystalline morphology of different structures was also evaluated. The thermal behaviors of synthesized copolymers are explored comprehensively. Finally, mechanical properties alteration and enhanced water absorption results are reported. POLYM. ENG.
