A branched hydrophobicity associated with polyacrylamide
A branched hydrophobicity associated with polyacrylamide based on silica was synthesized successfully. The structure of the polymer was characterized by Fourier Transform Infrared Spectrometer (FT-IR), 1H Nuclear Magnetic Resonance (1H NMR) and Scanning Electron Microscopy (SEM). Several properties such as intrinsic viscosity, temperature resistance, salt tolerance, shear resistance and
Compared with partially hydrolyzed polyacrylamide (HPAM), HMPAM demonstrated superior properties on aspects of thickening ability, salt tolerance, temperature resistance and oil displacement

The influence of salt and temperature on the viscosity of a hydrophobically modified polyacrylamide-based (PAM-based) novel functional polymer (RH-4) was investigated. To study the viscosifying mechanism in brine solution, scanning electron microscope (SEM) was applied to observe the network microstructures of polymer solution.

synthesis. Therefore, the practitioner of EBM often needs to appraise primary studies and, develop and practice critical appraisal skills. A number of helpful “tools” are available (Table 1-6), several of which make use of a framework outlined by Sackett and colleagues.5 This asks three important questions about any study: 1.
