Acrylamide sodium acrylate

The simplest monomer, ethylenesulfonic acid, is made by elimination from sodium hydroxyethyl sulfonate and polyphosphoric acid. Ethylenesulfonic acid is readily polymerized alone or can be incorporated as a copolymer using such monomers as acrylamide, aHyl acrylamide, sodium acrylate, acrylonitrile, methylacrylic acid, and vinyl acetate (222). Styrene and isobutene fail to copolymerize with ethylene sulfonic acid. [Pg.83]

Anionic polyacrylamide was prepared by gamma radiation-initiated copolymerization of acrylamid with sodium acrylate in aqueous solution at optimum conditions for the copolymerization [17]. The copolymerization process produces water-soluble poly (acrylamide-sodium acrylate [pAM-AANa] of high molecular weight [17,54]. [Pg.120]

In previous works [18-20,23,102] water-soluble polymers such as polyacrylamide (pAM), polysodium acrylate (pAA Na), poly(acrylamide-sodium acrylate) (pAM-AA Na), poly(acrylamide-diallyethylamine-hy-drochloride) (pAM-DAEA-HCl), and poly(acrylamide-sodium acrylate-diallyethylamine-hydrochloride) (pAM-AANa-DAEA-HCl) were used in the recovery of cations and some radioactive isotopes from aqueous solutions. It was found that the floe is formed between the added polymer and ions of the solution in the flocculation process with the formation of a crosslinked structure. The formed cross-linked structure is characterized by [103-105] ... [Pg.128]

The hydrolysis of polyacrylamide and acrylamide/sodium acrylate copolymers has been extensively studied [1,2,3,5,6,7,8,-9,10], in relatively strongly alkaline conditions, above pH 12. These studies demonstrated that the hydrolysis of the amide groups is hydroxide-catalyzed and that neighboring ionized carboxyl groups in the polymer inhibit the hydrolysis by electrostatic repulsion of the hydroxide ions. Senju et al. [6] showed that at temperatures up to 100°C, there is an apparent limit to the extent of hydrolysis of polacrylamide when approximately 60% of the amide groups are hydrolyzed. [Pg.108]

The polymerization of acrylamide (AM) and the copolymerization of acrylamide-sodium acrylate in inverse microemulsions have been studied extensively by Candau [10,11,13-15], Barton [16, 17], and Capek [18-20]. One of the major uses for these inverse microlatexes is in enhanced oil recovery processes [21]. Water-soluble polymers for high molecular weights are also used as flocculants in water treatments, as thickeners in paints, and retention aids in papermaking. [Pg.261]

The oil structure influence on the formulation is illustrated in Figure 1. It represents the minimum percentage of emulsifiers required to induce the transition aacro-raicroeaulsion versus their HLB values for monomer-water mixtures dispersed in different oils. It can be seen that in the case of acrylamide (AH) or acrylamide-sodium acrylate (Aa) mixtures, the amount of surfactant needed to form a microemulsion is much larger for toluene or cyclohexane than for Isopar K (11,12[). When methacrylcxyethyltrimethylammonium chloride (HA0OU.AT) is the monomer, the optimal conditions are obtained in cyclohexane. These results closely follow the differences calculated for the solubility parameters between oils and lipophiles as shown in Table I. [Pg.49]

These salting-out effects are partly responsible for the high HLBopt values found experimentally (see Figure 1). At a given temperature, the HLB of the blend is made more lipophilic on addition of an electrolyte monomer. The HLBopt has to be shifted to higher values in order to counterbalance the solubility decrease in water. Thus, the HLBopt measured is an apparent value, the effective one being that obtained in the absence of electrolyte. Figure 5 shows the increase in the HLBopt value observed when the ionic monomer content in an acrylamide-sodium acrylate feed stock increases from 0 to 65% (11). Vhen the monomer used is not an electrolyte (acrylamide), a similar curve is obtained by addition of a non polymerizable salt such as sodium acetate. [Pg.53]

The microstructure of acrylamide-sodium acrylate copolymers was determined by NMR (36). The monomer sequence distribution was found to conform to Bernouillian statistics and the reactivity ratios of both monomers were close to unity. These results which differ from those obtained for copolymers prepared in solution or emulsion (37) confirmed a polymerization process by nucleation and interparticular collisions. [Pg.57]

Statistical copolymers were reported for N-vinylimidazole and 13b [50], for acrylamide with 9a [11], 9b [12], and 9c [13], and for terpolymers of acrylamide, sodium acrylate, and 9b [51]. Several hydrolytically stable am-monioacetate and pyridiniocarboxylate monomers based on isobutylene with variable length of hydrophobic side chains did not homopolymerize, but these monomers with surfactant properties are suited for copolymerization with electron-poor monomers [52]. [Pg.168]

Copolymerization was initiated with azobis(isobutyronitrile) (AIBN) with the following monomers acrylamide, allyl acrylamide, sodium acrylate, acrylonitrile, methacrylic acid and vinyl acetate. In all these cases, the partner monomer was more reactive and preferentially incorporated in the copolymer. Less-polar or nonpolar monomers, such as styrene and isobutene, failed altogether to copolymerize. [Pg.881]

Figure 1 Pseudo ternary phase diagram. The dashed line (- -) is the boundary between the microemulsion (left) and emulsion (right) domains in the absence of monomers, i.e., in pure water. Addition of monomers (acrylamide + sodium acrylate) to water (1.25 mass ratio) extends the microemulsion domain up to the lull line (entire white area). Polymerization reactions have been carried out in the M area. (Isopar M is the oil). (From Ref 16.)...
