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).

Which products are produced by pyrolysis of PAA at 450 °C?

Pyrolysis of PAA at around 450 °C produces many products (e.g., amides, imides, nitriles, ketones, aldehydes, and acrylamide oligomers). Acrylamide, which is a possible carcinogen, is produced abundantly in various industries, and, therefore, continues to be a cause for concern.

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).

Does thermal decomposition of PAA cause acrylamide release?

Thermal decomposition of PAA under certain conditions has been reported to cause the release of acrylamide , and at cooking temperatures, degradation reactions are likely to occur . Therefore, a thorough understanding of its thermal behavior is of crucial importance for end-use applications.

What is pyrolysis gas chromatography?

Pyrolysis gas chromatography is one of the methods that has been used for a long time to analyze polymers qualitatively and quantitatively. This technique also allows one to study comonomers with similar structures. There are numerous papers on the thermal decomposition and decomposition products of polyacrylonitrile homopolymer [5-10].

Who funded the study acrylamide from polyacrylamide?

This study was supported, in part, by a grant from the France–Japan Sasakawa Foundation (Code 11-PT/14) and a Grant from the JSPS (Code 21-09706). Correspondence to Toshihiro Fujii. Kitahara, Y., Okuyama, K., Ozawa, K. et al. Thermal decomposition of acrylamide from polyacrylamide.
