In this research, a novel relatively long chain aliphatic polyester poly(octamethylene succinate) (POS) with a high weight-average molecular weight of 1.05 × 105g/mol was synthesized from succinic acid and 1,8-octanediol via a melt polycondensation method. POS was a semicrystalline polyester with a glass transition temperature of −53 °C and an equilibrium melting point temperature of 72.5 °C. With an increase in crystallization temperature, the overall crystallization rate and spherulitic growth rate of POS gradually decreased. Due to its high molecular weight and relatively long chain chemical structure, POS displayed relatively good mechanical properties with the Young's modulus, tensile strength, and elongation at break being 526 ± 8 MPa, 12.0 ± 0.3 MPa, and 165 ± 24%, respectively, thereby making it a potential candidate to find end use as a packing material.
