Biodegradable and bioresorbable polyesters (BBPEs) are a widespread class of aliphatic polymers with a plethora of applications in the medical field. Some reports speculate that these polymers have intrinsic antibacterial activity as a consequence of their acidic degradation by-products. The release of organic acids as a result of the hydrolytic degradation of BBPEs in vivo and the resulting pH...
Nowadays, “green” is a hot topic almost everywhere, from retailers to universities to industries; and achieving a green status has become a universal aim. However, polymers are commonly considered not to be “green”, being associated with massive energy consumption and severe pollution problems (for example, the “Plastic Soup”) as a public stereotype. To achieve green polymers, three elements sh...
Aliphatic and aromatic polyesters of hydroxycarboxylic acids are characterized not only by biodegradability, but also biocompatibility inertness, which makes them suitable for use in different applications. Polyesters with high enzymatic hydrolysis capacity include poly(lactic acid), poly(ε-caprolactone), poly(butylene succinate) adipate-co-terephthalate), succinate-co-adipate). At the same tim...
Plastic materials play a pivotal role in modern society. Finding sustainable alternatives to established fossil-based polymers is an important part of the effort reduce environmental impact sector. 1,4:3,6-dianhydrohexitols (isosorbide, isomannide and isoidide) are group biobased diol monomers that promising for synthesis polyesters. Their rigid molecular structure imparts favorable material pr...
