WebMar 25, 2010 · Alginate depolymerization under hydrothermal conditions occurred in a manner that initially released mannuronic acid (M) and then was followed by the release of guluronic acid (G). Monosaccharides were generated through the hydrolysis of the glycosidic bonds between the unit monomer with different selectivities among M–M, M–G and G–G ... WebJan 1, 2024 · Thermal degradation behavior of pristine PMMA and PCN was investigated using the TGA method. Thermal decomposition of pure PMMA (A) is a three-step process (Fig. 13–2). The first step occurs at around 100°C and is related to decomposition of head-to-head configuration and evaporation of impurities and solvent residue.

Thermal depolymerization (TDP) is the process of converting a polymer into a monomer or a mixture of monomers, by predominantly thermal means. It may be catalysed or un-catalysed and is distinct from other forms of depolymerisation which may rely on the use of chemicals or biological action. This process … See more For most polymeric materials thermal depolymerisation proceeds in a disordered manner, with random chain scission giving a mixture of volatile compounds. The result is broadly akin to pyrolysis, although at higher temperatures See more • Thermal treatment • Mechanical heat treatment • Wet oxidation • Staged reforming See more Some materials thermally decompose in an ordered manner to give a single or limited range of products.
