Amino acid-based bioanalogous polymers. Synthesis, and study of regular poly(ester amide)s based on bis(?-amino acid) ?,?-alkylene diesters, and aliphatic dicarboxylic acids

Synthesis and Characterization of Biodegradable Poly(ester amide)s with Pendant Amine Functional Groups and In Vitro Cellular Response

“…The GPC data of the PEA polymers are summarized in Table . All of PEA-Z-Lys polymers have similar molecular weight and molecular weight distribution, which were consistent with our prior report . When comparing with interfacial polymerization technique, we obtained much higher molecular weights of PEAs from the polycondensation reaction .…”

“…Typical DSC traces of these PEAs are shown in Figure . For the PEA-Z-Lys-0 (PEA without l -lysine units), the T g is 32.35 °C, which is consistent with our previous report . The T g of the protected PEA-Z-Lys-25 was 19.85 °C, about 12 °C lower than that of PEA-Z-Lys-0.…”

Synthesis and characterization of novel biodegradable unsaturated poly(ester amide)s

“…The FTIR spectra are shown in Figure 2, and their main absorption bands, such as those of the ester groups (∼1740 cm −1 ), have been assigned as detailed later. The IR spectral data and the T m values of PB and PH are all in agreement with those reported in the literature 13. The absorptions of CC in unsaturated PBe were around 1652 cm −1 .…”

“…The structures of NA, NS, and NF were all confirmed with FTIR and NMR spectra (as described later in detail). The IR spectral data and T m values of NA and NS are all in agreement with those reported in the literature 13. The FTIR spectra are shown in Figure 1, and the main absorption bands of these monomers have been assigned as described later.…”

Synthesis and specific biodegradation of novel polyesteramides containing amino acid residues

“…All the polyesteramides synthesized are insoluble in chloroform. This is quite different from the reported results that the polyesteramides containing α‐amino acids were generally soluble in chloroform 10, 11. Polyesteramides, except for those containing Gly residues, are soluble in aprotic polar solvents such as DMF and DMSO.…”
