Study On Synthesis And Solution Properties Of Amphiphilic Macromolecule P(AM-TBAM-NMMAD)

With the rapid development of the economy as well as the popularity of theautomotive industry, the petroleum resources has gradually become the one ofsignificant factors that limits to the economic growth steadily. It is the focus andattention how to design and synthesis the new ultra-high molecular weightamphiphilic polyacrylamide with hydrophobic monomer to improve the output of oilfor the many scientist.The amphiphilic polymer P(AM-TBAM-NMMAD) was researched byorthogonal experiment methods with the excellent heat resistance and salt tolerancebased on the the application of the product. The new hydrophobic monomerN-(2,3,3-trimethylbutan-2-yl)acrylamide (TBAM), the cationic monomerN’-methyl-N’-(2-methyldodecan-2-yl)acrylohydrazide (NMMAD) and the acrylamidewere synthesised and the dynamic viscosity was choosed as the response value tofilter the amount of initiator when the concentration of the P(AM-TBAM-NMMAD)solution was the1500mg/L. The optimal amount of initiator was obtained byorthogonal experiment. A series of the functional monomer was polymerized as thedifferent monomer feed composition rate and the other synthesis condition was keptuncharged. The1500mg/L polymerization dynamic viscosity was measured andcompared in the aqueous solution. The formulation of polymerization was choosedregard as the excellent oheological properties in the twice water.The macroscopic rheological behavior,micro-aggregation behavior as well as thetemperature and saltthe performance was disscussed according to fit the recommandof rare the high temperatural and high salty aqueous environment in order to achievethe two kinds of polymer which own higher rheological properties based on thescreening of the orthogonal experiment. Since the functional group rate of the twokinds of chains is different, the theory was expected to provide some supports aboutthe phonominant to compare the three categories in order to improve the capacity ofraring the high temperature and salty. Based on the research of the characteristics of this new type of temperature andsalt polymer P (AM-TBAM-NMMAD), the conclusions was obtained,(1)Theamphilic polymers P1, P2was synthesised by the orthogonal screening ofpolymerization with temperature and salt;(2) Conbined the aggregation behavior andthe rheological properties of the amphiphilic polymer P (AM-TBAM-NMMAD), themorphology of the amphiphilic polymer aggregation in aqueous solution showedspatial reticular. With increasing concentration, the formation of spatial network ismore dense and it is the important theoretical basis for the amphiphilic polymersolution with high rheological properties;(3) Comparing different salinity andtemperature on the impact of amphiphilic polymer solution, the amphiphilic polymerP(AM-TBAM-NMMAD) has the better effect than the conventional commerciallyavailable polymer flooding oil (sample S) for the comparison in the high temperatureand salinity environment based on the orthogonal experiment formulation. The resultsshows that the amphiphilic polymer has a good application prospects and wasexpected of great theoretical significance to research the excellent the amphiphilicpolymer with the high temperature and salty.
