Plastics are one of the most important materials in our daily lives due to their versatility, cheap price, easy production and attractive properties. However, large production volumes and largely linear use create huge amounts of plastic waste and environmental pollution. New materials should be designed from biobased resources and with sustainable end-of-life management in mind to integrate plastics in a circular economy. Here, we present facile synthesis of polyimine-amides starting from lignin derivable monomers and different diamines and triamines to yield corresponding linear and cross-linked polyimine-amide polymers with attractive properties. All the monomers and polymers were characterized for structure and thermal properties by 1D and 2D NMR, FTIR, TGA, DSC and DMA. In addition, thanks to the dynamic imine-bond, the crosslinked polyimine-amides demonstrated rapid stress-relaxation, shape memory, self-healing and mechanical reprocessing properties. Finally, closed-loop chemical recyclability of the synthesized polyester-imines under mild conditions was illustrated.
