Thermal decomposition behavior and mechanism study of
The thermal decomposition behavior of polyacrylamide poly (methacryloyloxyethyl trimethylammonium chloride-acrylamide) (P(DMC-AM)) was studied by means of TG and DSC under nitrogen atmosphere at temperature range of 323.15–823.15 K. The effect of cationicity on thermal stability was discussed. The TG/DSC curves indicated that the decomposition process of P(DMC-AM) included three steps, and，Modifying effect of anionic polyacrylamide dose for cement Anionic polyacrylamide replaces methyl cellulose to modify 3D printing materials. ?. Flowability, printability and microstructure of 3DP material are tested. ?. Physical-mechanical properties of 3DP material are analyzed. ?. New 3DP material can improve buildability and increase the deformation rate. ?.，Anionic Polyacrylamide Flocculant, Anionic Polyacrylamide Anionic Polyacrylamide (APAM) Anionic Polyacrylamide is produced when acrylamide is polymerized with an anionic comonomer. Water soluble Polyacrylamide have been used for decades to facilitate solidliquid separations in wastewater and drinking water treatment, the pulp and paper industry, aquaculture, and many other industrial processes.

Theoretical studies of hydrolysis and stability of
Water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers are among the most commonly used chemicals in oilfield applications. In polymer-augmented water-flooding Enhanced Oil Recovery (EOR) processes, HPAM polymers are often used as mobility-control agents to increase the viscosity of stimulation fluids in,β-Cyclodextrin modified anionic and cationic acrylamide In the paper, to introduce the inclusion function of β-cyclodextrin into acrylamide polymers, the novel anionic and cationic polymers were synthesized by aqueous free-radical copolymerization. Furthermore, FI-IR and SEM characterizations confirmed the synthetic products contained the structures of AM, A-β-CD and NaAA or DMDAAC.
