The aim of this work is to obtain optically and biologically active poly(urethane-imide)s (PUIs) using N,N’-(pyromellitoyl)-bis-l-tyrosine dimethyl ester (5) as a chiral and biologically active diphenolic monomer. Step-growth polymerization of diol 5 with various aliphatic and aromatic diisocyanates was carried out by gradual heating technique. The resulting PUIs were characterized with FT-IR, and...
N,N′-Bis[2-(methyl-3-(4-hydroxyphenyl)propanoate)]isophthaldiamide (5), a novel diol monomer containing chiral group, was prepared by the reaction of S-tyrosine methyl ester (3) with isophthaloyl dichloride (4a). A new family of optically active and potentially biodegradable poly(ester-amide)s (PEAs) based on tyrosine amino acid were prepared by the polycondensation reaction of diol monomer 5 with...
