Polyacrylamide - an overview | ScienceDirect Topics

Polyacrylamides (PAMs) are relatively inexpensive polymers that are easily formulated to high molecular weights on the order of several million g/mol. PAM was first used in the paper industry in the mid-1950s.

Mechanical degradation of polyacrylamide at ultra high deformation

Chemical degradation alone caused about a 1.7-fold reduction in MW compared to the more than 3-fold reduction due to mechanical degradation alone, although previous studies have demonstrated that there will be significantly more chemical degradation after longer time exposure (>24 h) to the oxygen radicals at these low pH conditions. 27 The combination of mechanical and chemical degradation

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

Molecular Dynamics-Assisted Design of High Temperature-Resistant

Polyacrylamide has promising applications in a wide variety of fields. However, conventional polyacrylamide is prone to hydrolysis and thermal degradation under high temperature conditions, resulting in a decrease in solution viscosity with increasing temperature, which limits its practical effect. Herein, combining molecular dynamics and practical experiments, we explored a facile and fast
