摘要：

The relationship between the molecular configuration and bulk behavior of partially hydrolyzed hydrophobically modified polyacrylamide (HMHPAM) in aqueous solution was studied via dissipative particle dynamics (DPD) simulation. The influence of the polymer concentration, polymerization process, degree of hydrolysis, and the hydrophobic modified group of HMHPAM on the polymer solution, especially the extent of expansion of the polymer and the viscosity of the polymer solution, were investigated quantitatively by calculating the root-mean-square (RMS) end-to-end distance of the polymer and the water molecule diffusivity. The influencing mechanisms of the type and the arrangement of the repeating unit of the polymer chains on the HMHPAM solution properties were studied to direct the practical synthesis, modification, and application of the polymer.
