Biodegradable Flame Retardants for Biodegradable Polymer [PDF]

open access: yesBiomolecules, 2020
To improve sustainability of polymers and to reduce carbon footprint, polymers from renewable resources are given significant attention due to the developing concern over environmental protection. The renewable materials are progressively used in many technical applications instead of short-term-use products.

Biodegradation of polyhydroxyalkanoates [PDF]

open access: yesFEMS Microbiology Letters, 1992
Degradation of poly(3-hydroxybutyrate) and copolymers with 3-hydroxyvaleric acid was investigated in natural environments, and the microorganisms involved were isolated and identified. The influence of abiotic and biotic factors on the degradation is discussed.

Biodegradable Polydepsipeptides [PDF]

open access: yesInternational Journal of Molecular Sciences, 2009
This paper reviews the synthesis, characterization, biodegradation and usage of bioresorbable polymers based on polydepsipeptides. The ring-opening polymerization of morpholine-2,5-dione derivatives using organic Sn and enzyme lipase is discussed. The dependence of the macroscopic properties of the block copolymers on their structure is also presented.

Predicting biodegradation [PDF]

open access: yesEnvironmental Microbiology, 1999
Biodegradation is important for natural and industrial cycling of environmental chemicals. Industries and government regulators increasingly seek to know the fate of chemicals in the environment and thus prevent potential negative impacts on human or ecosystem health. However, millions of organic compounds are known, and most will remain unstudied with
