| Abstract: | The depletion of petroleum-based fossil resources and ever-increasing environmental problems are serious issues in the production of polymeric materials. An increasingly important approach is to obtain the building blocks used in the production of these materials from renewable sources of natural origin. In the present study, bio-sourced tartaric acid-based tartarimides were evaluated as monomeric diol compounds to synthesize polyurethane polymers. Structurally diverse tartarimides were conveniently obtained from the condensation reactions of tartaric acid with various primary amine compounds. The diol structure of the generated tartarimides allowed to access polyurethanes along with the polymerizations of diisocyanate monomers. Copolymers in the range of 22.9 kDa to 29.3 kDa molecular weights were obtained with moderately high total monomer conversions (up to 96%). Depending on the tartarimide and diisocyanate monomers employed during polymerization, copolymers with different physical and thermal properties were generated. By utilizing tartarimides carrying furan and alkene functionalities, side chain reactive polyurethanes were synthesized. These reactive polymers were evaluated in post-polymerization modification and crosslinking processes by using radical thiol-ene and Diels-Alder based click reactions. The results obtained in this study demonstrated that the bio-sourced tartarimides could provide a convenient access to structurally tailorable polyurethane polymers that are important materials in various applications.
