Tuning the physical properties of malleable and recyclable polyimine thermosets: the effect of solvent and monomer concentration

The morphological, mechanical, and thermal properties of polyimine films were investigated under different reaction conditions. Polyimines with Young's modulus of 0.03-2.04 GPa could be obtained from the same monomer combinations. Our study shows that polyimine properties are determined by the combined effect of solvent choice and polymerization rate.
