Synthesis, characterization and properties of a castor oil modified biodegradable poly(ester amide) resin

Synthesis and characterization of poly(ester amide) from remewable resources through melt polycondensation

“…Fonseca et al [7] synthesized novel PEAs from glycine and L-lactic acid by interfacial polymerization, the method needs to be optimized to afford a higher molecular weight and a narrow molecular weight distribution. Pramanik et al [8] reported the synthesis of castor oil modified biodegradable PEAs with higher thermal stability. PEA based on caprolactone and 11-aminoundecanoic acid has also been reported by Qian et al [9].…”

Biodegradable polymers from monomers based on vegetable oils

“…The ester bonds could be degraded in the presence of lipase. The obtained adhesion strength, abrasion resistance, scratch hardness, gloss, impact strength and mechanical properties suggest applications in polymeric surface coatings [95,96].…”

“…In addition, the incorporation of aliphatic and aromatic species in polymer backbones improved significantly the biodegradability and biocompatibility, which are important parameters in biomedical and environmental applications [92][93][94]. Linseed [92], pongamia glabra [93], Nahar [94] and castor oils [95,96] In one study, biodegradable hyperbranched polyesteramides were prepared with maleic anhydride, phthalic anhydride and isophthalic acid from N,N-bis(2--hydroxyethyl) ricinoleic fatty amide. The weight average molecular weight of synthesized oligomers was found to be 2300 g mol −1 with dispersity of 1.40.…”

“…Because of the presence of numerous ester linkages in polymer backbones, the thermoset could be biodegraded using P. aeruginosa bacteria. The summarized the fatty acid based thermoset could be potentially used as biodegradable thin film material [95,96].…”

Castor oil–citric acid copolyester for tissue augmentation

“…The iodine value is correlated to the concentration of double bonds in the polymer sample. The iodine value of the crosslinked polymer was ~84 g, while for castor oil, it is reported to be 80–90 g …”
