Thermoplastic elastomers have attacked increasing attention as alternatives to traditional rubbers due to a combination of rubber-like properties such as high flexibility and heat resistance, along with their thermoplastic nature like extrusion and injection molding. In this study, we have synthesized poly(carbonate ester)-based thermoplastic elastomer (TPCE) using metal-free catalytic procedure. TPCEs were prepared in the presence of acid-base organocatalyst using dimethyl-2,6-naphthalenedicarboxylate as hard segment (HS), cyclic carbonates and lactones as soft segment (SS), and 1,6-hexanediol as chain extender. TPCEs with different HS and SS ratios were successfully produced and their mechanical properties were then investigated by universal testing machine, differential scanning calorimetry, dynamic mechanical analysis.
