Abstract

Butadiene is one of the most widely used materials in the Iran polymer industry. In order to use this material in the first step, the inhibitor must be separated. Consequently, at the start of the project, the separation of Tert butylcatechol inhibitors from butadiene was studied by the adsorption process on active alumina. The results of the condensed butadiene gas chromatography–mass spectrometry test indicate that, by using the active alumina as an adsorbent, the tert butylcatechol will be removed completely. In the next step, 1,3 butadiene, acrylonitrile, acrylic acid acid terpolymer, which one of its applications is manufacturing of artificial teeth, was synthesized by emulsion...

Abstract

Among the methods for increasing chemical oil extraction,the polymeric flood method has the most commercialization capability.However,most commonly used polymers such as Hydrolyzed Polyacrylamide (HPAM) are not able to withstand high levels of salinity and high temperatures.To overcome these problems,in this project,new types of polymer nanostructures were synthesized with hydrophobic groups consisting of styrene (hydrophilic monomer) and malic anhydride (hydrophilic monomer) acrylamide (hydrophilic monomer). These polymers were synthesized by reversible mini-emulsion by adjusting the synthesis conditions for the purpose of producing the terpolymer with suitable conditions for tolerating...

Simulation and Experimental Study in Inverse Emulsion Polymerization of Acrylamide, Styrene and Maleic Anhydride as Drag Reducing Agent

, Ph.D. Dissertation Sharif University of Technology Matloob Moghaddam, Mojtaba (Author) ; Ramazani Saadatabadi, Ahmad (Supervisor)

Abstract

This thesis presents the synthesis of terpolymers composed of acrylamide (AM), styrene (St), and maleic anhydride (MAH) monomers, utilizing varying concentrations of the reaction components. The synthesis was conducted via inverse emulsion of water in cyclohexane (20/100), employing AIBN as initiator and Span80 as a surfactant. Various analytical techniques, including FTIR, NMR, SEM, viscometry, DLS, GPC, EA, EDS were performed on the samples. Additionally, the impact of polymer addition in water on the reduction of pressure drop was evaluated. Acrylamide is an inexpensive and water-soluble monomer that serves as a primary building block for producing high molecular weight polymers that are...
