Thermal depolymerization is an industrial process of breaking down various waste materials into crude oil products. The materials are subjected to high temperatures and pressure in the presence of water, thereby initiating hydrous pyrolysis. As a result, the long chain polymers of the materials are depolymerized into short chain monomers.

Daliang Guo, a,b,c,d Bei Liu, e,f Yanjun Tang, a Junhua Zhang, a XinXing Xia, a,g, * and Shuhua Tong g, * The effects of reaction parameters on catalytic depolymerization of alkali lignin in sub- and super-critical ethanol were investigated using a high pressure autoclave, and the liquid oil and solid ...
Durante la síntesis del azul ultramarino, la materia prima utilizada es usualmente caolín, carbonato de sodio, cuarzo, azufre y brea, la cual es calcinada a 800°C originando la estructura del ...
Depolymerization is also related to production of chemicals and fuels from biomass. In this case, reagents are typically required. A simple case is the hydrolysis of celluloses to glucose by the action of water. Generally this process requires an acid catalyst: H(C 6 H 10 O 5) n OH + (n - .
D.Yu. Murzin, I.L. Simakova, in Comprehensive Inorganic Chemistry II (Second Edition), 2013. 7.21.3.2 Depolymerization. Depolymerization of biomass does not require such harsh conditions (high temperatures) as pyrolysis or gasification. The industrial pulping of wood is performed at 150–180 °C, resulting in delignification, that is, the decomposition of lignin and hemicellulose.
Depolymerization of PU waste was studied using lead acetate and zinc acetate as catalysts. Both the catalysts were taken from 0.4 g to 1.2 g using, 5 g of PU waste in 300 ml water at temperature of 180 0 C and autogenious pressure of 160 psi for reaction time of 60 minutes.

Se tomaron alícuotas de 0.1 ml del sobrenadante por triplicado y se mezclaron con el reactivo enzimático glucosa oxidasa/ peroxidasa; se incubó por 10 min a 50 °C y se midió la absorbancia a 510 nm en un espectrofotómetro Cary 1E- UV. Los cálculos de concentración se realizaron a partir del estándar .

Del análisis de la superficie de las muestras usando SEM, se aprecia la forma y tamaño de las diatomáceas dentro de la matriz de caolín, con un diámetro aproximado de 20 μm y una porosidad interna del orden de los nanometros.
The invention relates to a method for depolymerizing starch comprising mixing a starch material with an ionic liquid solvent to dissolve the starch, and then treating the dissolved starch by agitating at a temperature and for a period for time to effect depolymerization of the starch into desired depolymerization products.

Depolymerization occurs during thermal decomposition of poly (dimethylsiloxanes) too. There are formed cyclic oligomers, mainly hexamethyltrisiloxane. Such oligomers are used as monomers in polysiloxanes synthesis. It is necessary to underline that during heating bulk of polymers degradates instead depolymerization. ...
Depolymerization. Polymers often undergo significant chemical changes over time when exposed to high temperatures. These changes have a dramatic effect on the service life and properties of the polymeric material. The deterioration of the physical and mechanical properties is often the result of bond breaking in the polymer backbone (chain ...
Chemically amplified resists that act through a polymer depolymerization mechanism can be broadly divided into two classes: those that act through a thermodynamically induced depolymerization mechanism, and those requiring catalytic cleavage of a polymer backbone. The former process depends upon the use of low-ceiling-temperature polymers that have been stabilized by suitable end capping.
