Controlled Ring-Opening Polymerization of g em -Dialkyl β -Lactams toward Melt-Processable and Chemically Recyclable Nylon-3 Polyamides
Aliphatic polyamides are indispensable engineering materials, yet the development of chemically recyclable variants remains challenging due to their strong interchain hydrogen bonding and high crystallinity. Here, we report a monomer design strategy based on α-gem-dialkyl β-lactams that enables the controlled synthes...
