Mechanism and regulation of high temperature and high salt tolerance polymer polymerization behavior

In this study, the molecular dynamics simulation of imidazole-modified polyacrylamide (VPAM) and polyacrylamide (PAM) system showed that the VPAM system containing imidazole-modified polyacrylamide (VPAM) had better cohesion-bonding effect than the PAM system without imidazole. Based on the imidazole-containing VPAM system, the cohesion properties of the functional monomers and the mechanism of the functional monomers in the process of cohesion were analyzed at high temperature and high salt, and the structure-activity relationships between the chemical structure of the functional monomers and the ratio of polymer monomers and the apparent cohesion properties were obtained.
