Preparation of High-Performance Copolyamide 6 via a Side-Methyl Topological Structure Design Strategy
To address the insufficient toughness and transparency of nylon-6 (PA6) caused by high crystallinity, this study proposes a copolymer strategy based on side-methyl structural regulation. A series of PA6/D6 copolyamides were prepared via in situ melt copolymerization of ε-caprolactam, 2-methyl-1,5-pentanediamine, and...
