Synthesis And Properties Of The Ternary Ion Water-soluble Hydrophobic Polymer

As the development of petroleum industry, the demands of polyacrylamides polymer are getting more and more. The general polyacrylamides has satisfied their needs. But the existing polymers with the capabilities of temperature resistance and salt resistance cannot meet the complex application condition. In order to widen the application scope, many researchers have made research on polyacrylamides polymer with the capabilities of temperature resistance and salt resistance.According to the analysis of many literature, this thesis takes the AM as the first monomer (increasing the molecular weight), AMPS as the second monomer (increasing the ability of bearing salt and temperature), quaternary ammonium cation with long chain as the third monomer (long chain provides the hydropHobic associative capability, quaternary ammonium advances the soluble capability of hydropHobic associative polymers ) to synthesize hydropHobic associative polymers by the polymeric ways of water solution. And it has studied the influence of the factors that reactive temperature, reactive time, pH value, amount of initiator, composition of monomers, density of monomers ect. on the apparent viscosity with the example of the ternary polymers which contain DM16 hydropHobic monomers. Two kinds of polymers are synthesized with ternary polymers which contain DM16 hydropHobic monomers on appropriate condition combining practice. The capabilities of temperature resistance and salt resistance of polymeric solution with different contents of AMPS(contrasting with dualistic sample AM/DM 16), hydropHobic content (contrasting with sample AM/AMPS) have been studied; The hydropHobic associative effect are better and temperature resistance, salt resistance are stronger as the hydropHobic groups increasing on definite scope of hydropHobic content; The capabilities of temperature resistance and salt tolerance of hydropHobic associative polymers with mezzo content of AMPS are better on the fixed ratio of hydropHobic content. At the same time it has contrasted with characteristic viscidity, K_h numerical values of Huggins and their influence of capabilities of temperature resistance, salt resistance, dilution shearing and shear resume of polymers which are synthesized with different hydropHobic chains and long hydropHobic monomers; In the same ratio of diluent solution of polymers, the characteristic viscidity of AM/AMPS/DM16 is higher than AM/AMPS/DM18, while K_h is smaller. In the same ratio of solution, the temperature resistance and salt resistance of AM/AMPS/DM18 are better than AM/AMPS/DM 16.
