Diallyl ammonium salts

The problem of backbone flexibility has not yet been addressed for polysoaps. The vast majority of polymers reported have very flexible backbones. Clearly there must be gradual differences in the flexibility of the polysoaps prepared, depending on the main chain spacer and the reactive moieties employed. E.g., polysoaps based on polystyrene [51, 83, 104, 130, 238, 277, 278, 288, 292, 319-323] or poly(/V,Af-dialkyl,iV,jV-diallyl-ammonium salt)s [161, 168, 199, 200] should differ from polyvinyl-esters [224, 225, 232], polybutadienes [168, 313] or aliphatic polysulfones [164, 168],... 

In this report, we describe four series of polysulfobetaines. Two systems are based upon acrylamido repeat units, while two are based upon cyclopolymers synthesized from diallyl ammonium salts. Solution behavior is discussed as functions of polymer concentration, polymer composition, concentration of added electrolytes, and pH. From these systematic investigations, it is demonstrated that the conformation of a polymer in dilute solution may be controlled by the careful design of polymer architecture, and the adjustment of environmental conditions such as NaCi concentration and pH. 

Sulfobetaine cydopolymers. The first sulfobetaine cyclopolymer series OGQ) consists of the copolymers of 6 with 8 (Scheme 6) (42,43). Compositional analysis of this series of cyclopolymers is listed in Table 3. Reactivity ratios, determined via nonlinear least squares analysis " of chemical compositions determined from gated-decoupled C NMR, indicate random incorporation of the comonomers (ri=1.14 r2=0.97). The five-membered ring structure common to polymerized diallyl ammonium salts was retained in the sulfobetaine mer unit. Weight average molecular weights for this series range from 3.04 x 10" to 6.03 x 10 g mol. Second virial coefficients decrease from 8.78 x 10"" to 2.50 x lO"" ml mol g as the amount of 8 incorporated into the copolymer increases. 

Polydimethyl-diallyl ammonium chloride is a strongly basic cation-active polymer. A mixture of polydimethyl-diallyl ammonium chloride and the sodium salt of carboxymethylcellulose, which is an anion-active polymer, is applied in an equimolar ratio [497] in aqueous sodium chloride solution. The proposed plugging composition has high efficiency within a wide pH range.

Free radical polymerizations may also be used to synthesize a host of cationic polyelectrolytes. Diallyl quaternary ammonium salts such as dimethyl-diallylammonium chloride, diallyldiethylammonium chloride, and diallylmethyl b-propionamido chloride are an interesting class of monomers which will... 

Quaternary ammonium polymers were first discovered by Butler and Bunch (13) in 1949. In that investigation, tri- and tetraallyl quaternary ammonium salts were polymerized to form highly cross-linked water-insoluble polymers. In 1951, Butler and Ingley (14) reacted diallyl quaternary bromide salt to produce a polymer that was water-soluble and did not form a gel. Later, Butler (15) showed that the chloride ion form of diallylammonium monomers gave more useful polymers because of their higher molecular weights.
