The side groups in phosphazene polymers can be modified by further synthetic transformations. Sulfopropylation of [NP(0CH2CH20CH2CH2NH2)j,(0CH2CF3)y] with 1,3-propane sulfone gives polymers with up to half of the amino substituents converted to OCH2CH20CH2CH2NH(CH2)3SOjH groups which impart water solubility.

SP Sephadex C-25 cation exchangers whose dextran support, itself composed of propane-sulfonate-functionalized cross-hnked a-o-glucopyra-noside units, provides the chiral environment. Thus chiral eluents are not always necessary and achiral solvents can be used for separation. However, in some cases, separation is improved using an eluent containing a chiral ion [13]. 

Certain admixtures of carboxymethylhydroxyethylcellulose or copolymers and copolymer salts of N,N-dimethylacrylamide and 2-acrylamido-2-methyl-propane sulfonic acid (AMPS), together with a copolymer of acrylic acid, may... 

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. 

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.

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]. 

Other copolymers of acrylamide with the zwitterionic 3-(2-acrylamido-2-methylpropyldimethyl ammonio)- -propane sulfonate (AMPDAPS) monomer also have been examined. 

The NMR spectrum shown in Figure 5 was obtained by dissolving hydralazine hydrochloride in deuterium oxide containing 3-(trimethylsilyl)-1-propane-sulfonic acid sodium salt (DSS). The series of peaks at 0, 0.6, 1.8, and 3 ppm are all due to the DSS. The peak at 4.8 ppm is due to HDO which forms on exchange with the solvent and the peaks at 8.01 and 8.61 ppm are due to the aromatic protons. The NMR spectrum of the base (Figure 6) was obtained in a 1 1 mixture of dimethylsulfoxide-d,- deuterochloroform. 

Similar surfactant-stabilized colloidal systems have been reported by Albach and Jautelat, who prepared aqueous suspensions of Ru, Rh, Pd, Ni nanoparticles and bimetallic mixtures stabilized by dodecyldimethylammonium propane-sulfonate [103]. Benzene, cumene and isopropylbenzene were reduced in biphasic conditions under various conditions at 100-150 °C and 60 bar H2, and TTO up to 250 were obtained. 

Other novel bicelle systems composed of a mixture of l,2-di-0-dodecyl-sn-glycero-3-phosphocholine and 3-(chloramidopropyl)dimethylammonio-2-hydroxyl-l-propane sulfonate have been designed to orient proteins at low pH values and over wide temperature ranges [25].

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.
