The polymerization of nonconjugated diene monomers might be expected to afford polymer chains with pendant unsaturation and ultimately, on further reaction of these groups, crosslinked insoluble polymer networks. Thus, the finding by Butler et a .,, 03, n5 that polymerizations of diallylammonium salts, of general structure 8 [e.g. diallyldimethylammonium chloride (9)] gave linear saturated polymers, was initially considered surprising. 

We have studied stoichiometry of complex formation between DNA and PLL and found that the complexes formed in low-salt-buffer solutions are of a 1 1 charge ratio [92]. The same 1 1 stoichiometry was found experimentally for DNA complexed with other synthetic polycations of different nature in low-salt aqueous solutions [such as poly (diallyldimethylammonium chloride), poly(dimethyhmino)ethylene(dimethylimino)ethy-lene-l,4-dimethylphenylmethyl ene dichloride, andpoly(4-vinyl-A-methylpyridinium bromide)] [93].

Copolymers from the monomers AMPS, diallyldimethylammonium chloride (DADMAC), N-vinyl-N-methylacetamide (VIMA), acrylamides, and acrylates are particularly useful for fluid loss additives [824]. The molecular weights of the copolymers range from 200,000 to 1,000,000 Dalton. The copolymers are used in suspensions of solids in aqueous systems, including saline, as water binders. In these systems, the water release to a formation is substantially reduced by the addition of one or more of these copolymers.

Negatively charged species such as carboxylic acid group in acid-treated CNTs can attract positively charged enzymes from solution as long as the pH value of the enzyme solution is controlled to be lower than the iso-electric point of the enzyme thus, multilayer films of the enzyme can be formed by the layer-by-layer technique. For example, five layers of GOx can be immobilized on the electrode surface by alternatively dipping a poly(diallyldimethylammonium chloride (PDDA))-functionalized GC into a CNT solution and a GOx solution (pH 3.8). Figure 15.15 illustrates the preparation process for the formation of a multilayer film of GOx on the electrode.

Fabrication of organic thin films based on sponfaneous molecular assembly has been considered as one of fhe powerful approaches to create novel supramolecular systems. In this context, multilayer films were fabricated by layer-by-layer electrostatic deposition techniques based on the electrostatic interaction between dsDNA and the positively charged polymer poly(diallyldimethylammonium chloride) (PDDA) on GC surfaces. A uniform assembly of PDDA/DNA multilayer films was achieved, based on the adsorption of the negatively charged DNA molecules on the positively charged substrate [55].

Work with supported ionic liquids was extended to a cationic polymer, poly (diallyldimethylammonium chloride), which has quaternary ammonium functional groups (Fig. 16) 268). The extra-structural counter anion is Cl . The polymer was applied to simultaneously incorporate an ionic liquid and a transition-metal catalyst via a simple mixing of the components. Wilkinson s catalyst and [BMIM]PF6 were... 

The importance of intramolecular cyclization was emphasized when Butler and coworkers found that the radical polymerization of N, N, N, /V-diallyldimethylammonium chloride (DADMAC) gave soluble, uncrosslinked polymers with little or no unsaturation (Eq. 6-101) [Butler and Angelo, 1957 Butler and Ingley, 1951 Wandrey et al., 1999]. There is a very low tendency for radical IV to propagate intermolecularly and undergo crosslinking. The predominant reaction is intramolecular cyclization, and the product is a linear product with cyclic structures in the backbone. The reaction is referred to as alternating intra/intermolecular polymerization or cyclopolymerization. 

Polymers of N, N, N, A-diallyldimethylammonium chloride (DADMAC) (and its copolymers with acrylamide) are allyl resins in terms of the monomers used but are very different in properties since they are not crosslinked. Cyclopolymerization is the mode of reaction (Sec. 6-6b) and the polymers are water-soluble. Applications include potable and wastewater treatment (flocculation aid) and paper and textile industries (antistatic coating, reinforcement, color removal). 

PDADMA = poly(diallyldimethylammonium chloride) a positively, PSS = poly(styrenesulfonic acid), PAMPS = poly(2-acrylamido-2-methyl-l-propane sulfonic acid), and PFPVP = 4-vinyl-trideca-fluoro-octyl pyridinium iodide-co-4-vinyl pyridine. 

Preparation of glyoxalated poly(vinylamide-co-diallyldimethylammonium chloride)... 

An aqueous solution of poly(vinylamide-co-diallyldimethylammonium chloride) consisting of 91 wt% acrylamide was treated with sufficient glyoxal so that an amide/glyoxal molar ratio of 4 1, respectively, was obtained. Thereafter the mixture was treated with the dropwise addition of 5 wt% aqueous sodium hydroxide until the pH of the solution reached 9.2. Small additions of sodium hydroxide were administered as needed to maintain a constant pH of 9.2 for 30 minutes. 

Glyoxalated poly(vinylamide-co-diallyldimethylammonium chloride) containing 80% vinylamide content and having a molecular weight of 1900 Da was previously prepared by Guerro et al. (3) and used as handsheet additives.
