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.

Tumoko and coworkers [485] showed that polymers based on acrylamide, methyl propane sulfonic acid and butyl methacrylate in conjunction with poly(2 methacryloyloxyethyl phosphorylcholine-co-butyl methacrylate) are capable of suppressing platelet adherence. Similar results [486] were found on poly(gamma benzyl 1 glutamate-co-leucine) neutralized with sodium. [Pg.41]

Acrylamide monomer is a white crystal, available commercially as a 50 wt % aqueous solution. Acrylamide monomer can be polymerized to a very-high-molecular-weight (lO -lO g/mole) homopolymer, copolymer, or terpolymer. Polyacrylamide (PAM) is a nonionic polymer. The anionic polyacrylamide species can be obtained from the hydrolysis of the amide (—CONH ) functional group of the homopolymer, or from the copolymerization of acrylamide with an anionic monomer, such as acrylic acid (AA) or 2-acrylamino 2-methyl propane sulfonic acid (AMPS). Acrylamide can be copolymerized with a cationic monomer, such as dimethyl diallylammonium chloride (DMDAAC) or acryloyloxyethyl trimethyl ammonium chloride (AETAC), to form the cationic acrylamide polymer. Acrylamide can simultaneously react with anionic and cationic monomers to form a polyampholyte. The acrylamide homopolymer, copolymers, and terpolymers are synthesized (1-20) by free radicals via solution or emulsion or other polymerization methods. F. A. Adamsky and E. J. Beckman (21) reported the inverse emulsion polymerization of acrylamide in supercritical carbon dioxide. The product classes of acrylamide polymers include liquid, dry, and emulsion. [Pg.249]

The wear properties of four kinds of DN gels, which were composed of synthetic or natural polymers, were evaluated [47]. The first gel was a PAMPS/PAAm DN gel, which consists of poly(2-acrylamide-2-methyl-propane snlfonic acid) and polyacrylamide. The second gel was a PAMPS/PDMAAm DN gel, which consists of poly(2-acrylamide-2-methyl-propane sulfonic acid) and poly(NJ4 -dimethyl acrylamide). [Pg.243]

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]
