What is thermal decomposition of polymers?

This chapter discusses the thermal decomposition of polymers. Thermal decomposition of polymers is a subject of considerable interest for many practical purposes. The chemical processes occurring when a polymer is heated depend on the heating temperature, heating rate, and the atmosphere in which the heating takes place.

What is the thermal decomposition of polyacrylamide (Paa)?

With this technique, we investigated the thermal decomposition of polyacrylamide (PAA). Pyrolysis of PAA at around 450 °C produces many products (e.g., amides, imides, nitriles, ketones, aldehydes, and acrylamide oligomers).

Does cationic polymer P evolve during thermal decomposition?

In the present work, the thermal decomposition behavior of cationic polymers P (DMC-AM), synthesized in laboratory, was investigated in nitrogen by TG and DSC. The evolved gas during thermal decomposition process was analyzed by FTIR and MS.

Can thermal decomposition of polyacrylamide detect thermally unstable products?

It, therefore, offers the opportunity to monitor directly thermal byproducts on a real-time basis and potentially to detect thermally unstable products. With this technique, we investigated the thermal decomposition of polyacrylamide (PAA).

What are the thermal decomposition processes of synthetic polymers?

Various aspects of thermal decomposition processes of synthetic polymers are thoroughly discussed in various publications. Processes of particular interest are the reactions that occur when the polymer is heated at temperatures between 500°C and 800°C (considered the typical range for pyrolysis).

Why are thermal decomposition studies of polymers important?

Thermal decomposition studies of polymers are necessary as many applications depend on their thermal stability. To reach this goal, many techniques have been used such as gas chromatography, thermoanalysis, and mass spectrometry [18, 19, 20].
