“…The conductivity increases with the ratio of magnesium hydroxide ratio in MHPAM inorganic-organic composite polymer. A linear relationship is observed between the conductivity of MHPAM inorganic-organic composite polymer in aqueous solution at different concentrations which is in agreement with our previous study [9]. At the same concentrations, reduced viscosity was measured to determine intrinsic viscosity for MHPAM inorganicorganic composite polymers.…”

“…It is noted that no new chemical bond is formed when magnesium salts is premixed with polyacrylamide, which reveals that magnesium salt-polyacrylamide is a physical mixture. However, hydrogen bonding could be formed between magnesium hydroxide and electronegative nitrogen atom of polyacrylamide [9]. Physical properties: For the physical properties of inorganic-organic composite polymer, conductivity and intrinsic viscosity are taken into account.…”

Abstract:In this study, a series of inorganic-organic composite polymer was prepared. Magnesium hydroxide and polyacrylamide was composed in a composite matrix to prepare Mg(OH) 2 -PAM (MHPAM) inorganic-organic composite polymer. The characteristics of MHPAM inorganic-organic composite polymer was investigated in terms of chemical, physical, physical, thermal and morphological properties through FT-IR, conductivity, intrinsic viscosity, TGA and TEM, respectively. Results showed that the properties of MHPAM composite polymers varied with the compositions in the composite polymers. Different compositions of MHPAM inorganic-organic composite polymers were applied in removing reactive dye from aqueous solution. MHPAM inorganic-organic composite polymer with Mg(OH) 2 : PAM ratio of 90 : 10 gave the best dye removal (%) where it was able to remove 98% of reactive dye at pH 11.00 with a dosage of 500 mg/L. Kinetics study was carried out using different dye concentration and it was found that the experimental data fitted the pseudo-second-order model better compared to pseudo-first-order model.

“…One of the extensively employed polymers in petroleum engineering especially in EOR process partially hydrolyzed polyacrylamides (HPAMs) due to their moderately good solubility in water and reasonable economic [4]. As a definition, HPAMs are synthesized from acrylamide monomers; thus, they will have negatively charged linear chain macromolecules, in which some of their monomers are hydrolyzed by an electrolyte [5].…”

Abstract. Polymers applications have been progressively increased in sciences and engineering including chemistry, pharmacology science, and chemical and petroleum engineering due to their attractive properties. Amongst the all types of polymers, partially Hydrolyzed Polyacrylamide (HPAM) is one of the widely used polymers especially in chemistry, and chemical and petroleum engineering. Capability of solution viscosity increment of HPAM is the key parameter in its successful applications; thus, the viscosity of HPAM solution must be determined in any study. Experimental measurement of HPAM solution viscosity is time-consuming and can be expensive for elevated conditions of temperatures and pressures, which is not desirable for engineering computations. In this communication, Multilayer Perceptron neural network (MLP), Least Squares Support Vector Machine approach optimized with Coupled Simulated Annealing (CSA-LSSVM), Radial Basis Function neural network optimized with Genetic Algorithm (GA-RBF), Adaptive Neuro Fuzzy Inference System coupled with Conjugate Hybrid Particle Swarm Optimization (CHPSO-ANFIS) approach, and Committee Machine Intelligent System (CMIS) were used to model the viscosity of HPAM solutions. Then, the accuracy and reliability of the developed models in this study were investigated through graphical and statistical analyses, trend prediction capability, outlier detection, and sensitivity analysis. As a result, it has been found that the MLP and CMIS models give the most reliable results with determination coefficients (R 2 ) more than 0.98 and Average Absolute Relative Deviations (AARD) less than 4.0%. Finally, the suggested models in this study can be applied for efficient estimation of aqueous solutions of HPAM polymer in simulation of polymer flooding into oil reservoirs.
