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).

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 is the thermal degradation of polyacrylamide?

The thermal degradation of polyacrylamide has been studied by using thermogravimetry. The experiments were carried out over the temperature range 100–900 at four heating rates of 5, 10, 20 and 40°C /min and in a nitrogen atmosphere.

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 the activation energy of acrylamide decomposition?

The activation energy of the thermal decomposition of acrylamide exhibited different behaviors in different environments. Under nitrogen, the activation energy of acrylamide degradation was 143.02 kJ/mol. This information will be helpful in understanding acrylamide release from PAA.

How can EGA-Iams provide information on acrylamide thermal decomposition products?

Here, we describe how EGA–IAMS can provide information on the thermal decomposition products of PAA, including acrylamide, in a controlled environment. EGA–IAMS is a simple and fast method that can be used with a small sample size, allowing rapid qualitative and semi-quantitative analysis.
