Abstract A series of fully renewable poly(ester urethane urea)s (PEUs) were synthesized from bio-based starting
materials, e.g., the polyester diol, the diisocyanates including L-lysine diisocyanate (LDI) and isoidide
diisocyanate (IIDI), the chain-extenders including 1,4-diaminobutane (bDA), diaminoisoidide (iDA)
and di(aminobutyl) urea (b2
DA). It is found that the PEU based on the novel diisocyanate, IIDI, exhibits
satisfactory thermal and mechanical properties. The LDI-based PEUs show less favorable thermal and
mechanical properties than the IIDI-based counterpart, since the chemical structure of LDI is less regular than
that of IIDI. However, by introducing a urea-containing dimeric diamine (b2
DA) instead of the monomeric
diamines,… More >
