Abstract:

The construction of covalent adaptable networks (CANs) without requiring post-modification, complex monomer synthesis routes, or expensive materials is highly desirable for advancing the practical application of dynamic covalent chemistry. In this study, the commercially available acrylate monomer, diacetone acrylamide (DAAM) was first polymerized using a conventional, free radical polymerization method. Subsequently, the resulting polymer was cross-linked with amine-based agents under hot-processing conditions to form aliphatic imine-linked CANs. The obtained materials exhibited glass transition temperatures (Tg) ranging from 95 to 107 degrees C, along with good thermal stability, mechanical, and thermomechanical properties. All samples demonstrated mechanical recyclability with post-recycled specimens retaining approximately 80% of their original tensile strength and Young's modulus, indicating a slight deterioration. Gel content analysis and structural characterization of both pristine and recycled samples indicate that the observed reduction in mechanical properties and Tg (by 70 degrees C) originated from a decrease a cross-linking density and partial cleavage of aliphatic ketone moieties. Furthermore, the aliphatic imine structure endowed all samples with acid-triggered degradability. This facile strategy for fabricating acrylate-based imine CANs establishes a versatile framework for developing reprocessable and hydrolyzable polymeric materials.
