Biobased polyesters and other polymers from 2,5-furandicarboxylic acid: a tribu...
Sousa, Andreia F; Vilela, Carla; Fonseca, Ana C; Matos, Marina; Freire, Carmen S R; Gruter, Gert-Jan M; Coelho, Jorge F J; Silvestre, Armando J DMotivated by the general concern about sustainability and environmental issues, an intense search for renewable-based polymers has grown exponentially in recent years. This search definitely spotlighted polyesters derived from 2,5-furandicarboxylic acid, among other polymers, as some of the most promising, especially due to the resemblance of this renewable monomer to the well-known petroleum-based terephthalic...
Poly(ester amide)s based on (L)-lactic acid oligomers and α-amino acids: influe...
Fonseca, Ana C; Coelho, Jorge F. J.; Valente, Joana F. A.; Correia, Tiago R.; Correia, Ilídio J.; Gil, Maria H.; Simões, Pedro N.Novel biodegradable and low cytotoxic poly(ester amide)s (PEAs) based on α-amino acids and (L)-lactic acid (L-LA) oligomers were successfully synthesized by interfacial polymerization. The chemical structure of the new polymers was confirmed by spectroscopic analyses. Further characterization suggests that the α-amino acid plays a critical role on the final properties of the PEA. L-phenylalanine provides PEAs w...
