Abstract

Twenty seven poly (ester–urethane–amide) s (PEUAs) were synthesized from the reaction of α, ω-telechelic poly (ε-caprolactone) diols, 1, 6-hexamethylene diisocyanate, and three different diamide–diol chain extenders derived from ε-caprolactone and three aliphatic diamines with increasing length (n= 2, 4, and 6). The hard segment (HS) was designed to be crystalline and to introduce amide groups, more susceptible to hydrolysis than urethane or ...
