Abstract
The global sustainable development of the polymer industry is dependent upon the ease of synthesis and the replacement of petroleum-based elastomers with biobased equivalents. Here, we suggest the condensation polymerization of aliphatic diacids such as glutaric acid, pimelic acid, azelaic acid, and 1,4-butanediol with a catalytic amount of glycerol as a curing agent and dithiodicarboxylic acid as the dynamic covalent crosslinker to fabricate highly stretchable elastomers. The elastomers showed good extensibility, reprocessability, and self-healable properties. The molecular characterization and thermo-mechanical properties of the elastomer were investigated using Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry, and Dynamic Mechanical Analysis. The self-healing performance of the elastomers is ascertained by SEM analysis, where the presence of -S-S crosslinker provides a disulfide metathesis phenomenon which assisted in self-healing properties of the elastomer at low temperatures. The high elongation, thermal reprocessability, and self-healing nature of the polymers result in the successful preparation of biobased vitrimeric elastomer. The simplicity of preparing the elastomers by polycondensation process suggests that there are promising possibilities to generate environmentally friendly sustainable polymers with stimuli-responsive properties.
