A branched hydrophobicity associated with polyacrylamide based on silica: synthesis and solution properties

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), 1 H Nuclear Magnetic Resonance ( 1 H NMR) and Scanning Electron Microscopy (SEM). Several properties such as intrinsic viscosity, temperature resistance, salt tolerance, shear resistance and viscoelasticity of the polymer were evaluated. Experiment results had demonstrated that the introduction of vinyltriethoxysilane (VTS-SiO 2 ) and branching molecular structure could endow the polymer with excellent temperature tolerance capability, salt and shear resistant capability.
