Abstract
Polythiourethane polymer networks that can be processed and/or recycled are provided. Also provided are methods of forming the polythiourethane polymer networks using excess thiol and/or a dual catalyst system and methods for reprocessing and recycling the polyurethane polymer networks. The polythiourethane polymer networks are based on thiourethane dynamic chemistry.
