Do polyacrylamide-type polymers have good thermal stability?

Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions. Viscosity reduction of polyacrylamide-type polymers with good thermal stability was owing to polymer main chain degradation at harsh conditions.

What types of polyacrylamide products can Tianrun chemicals provide?

Tianrun Chemicals attaches great importance to customer needs, and we can provide five series of polyacrylamide products: anionic, cationic, nonionic, amphoteric, and emulsion according to customer requirements. Tianrun Chemicals is one of the drafters of the national standard for polyacrylamide and drinking water grade polyacrylamide.

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 is anionic polyacrylamide?

Anionic polyacrylamide is suitable for higher density, inorganic suspension substance with positive charge and is neutral or basic, with thick suspension particles of 1mm-10mm. Polyacrylamide comes in various forms such as granular, liquid oil emulsion, tablet, and block forms.

Which polymer thickening agent is a cationic polyacrylamide?

Zhang et al. , synthesized the polymer thickening agent DXGY-1, which is a cationic polyacrylamide. Its viscosity retention ratio in 12% HCl + 3% HF reached 82%. Liu et al. , synthesized a copolymer from AM, DMDAAC, and AMPS monomers and a cationic monomer X.
