Polyacrylamide degradation and its implications in environmental systems | npj Clean Water - Nature

The term ¡°polyacrylamide¡± is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which defines...

An approach to evaluate polyacrylamide-type polymers' long-term stability under high temperature and high salinity environment - ScienceDirect

The thermal stability of 12 commercial water soluble polymers was tested in this work. The long-term stability results are consistent with the TGA results. The two polymers showing good thermogravimetric stability exhibited significant viscosity retention in conventional long-term stability tests.

Thermal decomposition behavior and mechanism study of cationic polyacrylamide | Journal of Thermal Analysis and Calorimetry - Springer

Abstract 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¨C823.15 K. The effect of cationicity on thermal stability was discussed.

thermodynamic stability of polyacrylamide and poly

Thermodynamic stability of polyacrylamide and poly

Based on theoretical thermodynamic principles, the possibility of environmental degradation of polyacrylamide to its starting monomer was investigated. Theoretical electronic structure studies on the geometry and fragmentation energy of acrylamide and N,N -dimethyl acrylamide tetramer models were carried out using a first principles gradient corrected density functional approach.

Investigating physical behavior of polyacrylamide/polyacrylic acid interpenetrating polymer networks through atomistic molecular dynamics

A new comprehensive simulation model at atomistic level is proposed to investigate the miscibility and predict the glass transition temperature ( Tg) and mechanical properties of polyacrylamide/polyacrylic acid (PAAm/PAA) weakly interpenetrating polymer networks (IPN).
