Abstract
The objective of this study was to explore an environment-friendly route to synthesize nonisocyanate based poly(ester urethanes) of poly(1,10-bis(hydroxyethyloxycarbonylamino) decane-co-dicarboxylic acid) (PBDA) from renewable materials/resources. In specific, 1,10-bis(hydroxyethyloxycarbonylamino)decane (BHD) was first synthesized from ethylene carbonate and decamethylene diamine via the melt ring-opening reaction. Subsequently, the PBDAs with tunable properties were synthesized from BHD and five dicarboxylic acids (including three biobased ones of oxalic acid, sebacic acid, and itaconic acid) via the melt polycondensation reaction. The structural, physical, and mechanical properties of PBDAs were characterized by FTIR, NMR, XRD, GPC, TGA, and mechanical testing machine; additionally, the environmental stability was evaluated upon measuring the water absorption amount in deionized water and the degradation percentage in phosphate buffer saline. The results indicated that the PBDAs possessed reasonably go...
