Abstract Biobased oligo(butylene succinate)-based thermoplastic polyurethanes (TPUs) were prepared following a twostep polymerization process: condensation of succinic acid and butanediol and the chain extension of resulting
hydroxyl-terminated butylene succinate oligomers (OBS) in the presence of butanediol as chain extender and
isophorone diisocyanate (IPDI) as coupling agent. Mechanical and thermal properties of the elaborated TPUs
were evaluated in terms of hard segment and compared with those of commercial polybutylene succinate
(PBS), Bionolle 1001. Whatever the compositions, the ultimate tensile properties of OBS-based TPUs and
Bionolle 1001 were found to exhibit similar values (εr
≈ 400%, σr
≈ 40 MPa), which can be… More >
