Homopolymers and copolymers from amido-sulfonic acid or salt containing monomers can be prepared by reactive extrusion, preferably in a twin screw extruder [1660]. The process produces a solid polymer. Copolymers of acrylamide, N-vinyl-2-pyrrolidone, and sodium-2-acrylamido-2-methyl-propane sulfonate have been proposed to be active as fluid loss agents. Another component of the formulations is the sodium salt of naphthalene formaldehyde sulfonate [207]. The fluid loss additive is mixed with hydraulic cements in suitable amounts. [Pg.49]

However, the mechanism of action of filtration control additives is not yet completely understood. Examples are bentonite, latex, various organic polymers, and copolymers. Many additives for fluid loss are water-soluble polymers. Vinyl sulfonate fluid loss additives based on the 2-acrylamido-2-methyl-propane sulfonic acid (AMPS) monomer are in common use in field cementing operations [363]. The copolymerization of AMPS with conjugate monomers yields a fluid loss agent whose properties include minimal retardation, salt tolerance, high efficiency, thermal stability, and excellent solids support. [Pg.147]

Associative copolymers of acrylamide with N-alkylacrylamides, terpoly-mers of acrylamide, N-decylacrylamide, and sodium-2-acrylamido-2-methyl-propane sulfonate (NaAMPS), sodium acrylate (NaA), or sodium-3-acrylamido-3-methylbutanoate (NaAMB) have been shown to possess the required rheologic behavior to be suitable for enhanced oil-recovery processes [1184]. [Pg.205]

Type A copolymers and terpolymers have been prepared by copolymerizing vinyl pyridinium halides with alkali metal salts of sulfonate comonomers including vinylsulfonate, 2-acrylamido-2-methyl propane sulfonate, and p-styrene sulfonate (15-19). Methacrylamidopropyl-trimethyl ammonium chloride and p-styrene sulfonate have been terpolymerized with the hydrophilic monomer acrylamide (20,21). Type A copolymers and terpolymers have also been prepared from microemulsions of sodium 2-acrylamido-2-methyl-l-propanesulfonate and [2-(methacryloyloxy)ethyl]trimethylammonium chloride (22-25). [Pg.13]

The use of additives in aqueous emulsions for mist suppression has been only recently been explored (1,2,3). In particular, high molecular wei t polyethylene oxide EO) polymers have received considerable testing and have shown to have some degree of success in reducing mist. However, these polymers have a finite lifetime in the fluid before they shear degrade. Thus, this has led to the development of novel shear stable polymers derived from a highly hydrophilic sodium-2-acrylamido-2-methyl propane sulfonic acid (NaAMPS) monomer polymerized with hydrophobic monomers. (4)... [Pg.200]

Sodium-2-acrylamido-2-methyl propane sulfonic acid (NaAMPS) monomer was polymerized with a variety of hychophobic alkylacrylate and alkylacrylamide monomers. The reactions were performed as solution polymerizations in methanol using the redox radical initiator of sodium persulfate and sodium metabisulfite. [Pg.201]

Free radicd polymerization of 2-acrylamido-2-methyl propane sulfonic add (Lubtizol s AMPs monomer) or its soluble salt also yields sheet form, ionically conductive adhesive for use in biomedical electrodes (13). This mat ial exhibits uniform conductivity preventing the hot spots associate with localized current Additionally, the AMPs -based materials are inheroitly electrically conductive, not requiring the use of additional additives (e.g., salts). [Pg.298]
