Fully Bio‐Based TPUs From PLA/PTMC: Tunable Strength and Degradation Profiles

ABSTRACT This study synthesizes a series of fully bio‐based thermoplastic polyurethanes (TPUs) using poly(lactic acid) (PLA‐OH) and poly(trimethylene carbonate) (PTMC‐OH) as blended soft segments, L‐lysine ethyl ester diisocyanate (LDI) as the hard segment, and 1,4‐butanediol (BDO) as a chain extend...
