Acrylamide styrene

It is possible to develop novel polymer-polymer composites or blends by simultaneous or sequential polymerization of hydrophilic and hydrophobic monomers. Preliminary work on microemulsions contidning styrene/acrylamide... 

Bulk addition multipolymerization kinetics occurs when two monomers are employed. Bulk free-radical homopolymerizations and copolymerizations that are implemented in REX include a) styrene-acrylonitrile, styrene-methyl methacrylate, styrene-acrylamide b) methyl methacrylate-acrylonitrile, ABS c) acrylate ester mixtures d) ethyl acrylate-methacrylic acid and mixtures with other monomers e) methyl methacrylate f) 8-caprolactone and, n-isopropylacrylamide-acrylic... 

While possessing many of the key advantages of controlled/ living polymerization methods, nitroxide-mediated free-radical polymerizations do exhibit several limitations. The range of monomers that have been polymerized using nitroxide-mediated techniques include styrenics. acrylamides and (meth)acrylates but these have predominantly been reported in bulk polymerizations (i.e. without solvent) and are conducted at elevated temperature for long time periods. In addition, synthesis of the unimolecular initiator can prove troublesome (dependent upon the type required) and often requires extensive purification in order to attain sufficient purity levels to allow molecular weight control. 

NMR analysis has indicated [9b] that the olefin used does not isomerize during copolymerization. Various vinyl monomers copolymerize with SO2 such as vinyl chloride, styrene, acrylamide, and chloroprene. However, methyl methacrylate is reported [9b] to homopolymerize in SO2 when used as a solvent (cationially or radically) but not to form polysulfones (sulfur dioxide copolymers). 

The styrene-acrylamide latices lend themselves particularly well to modification of the functional groups on the particle surfaces without significantly affecting the particle diameters [81a, b]. 

At 30°C, treatment of 50 gm of a 20% solids styrene-acrylamide latex with 10 gm of 20% aqueous sodium hydroxide for various time periods (up to 5 hr) converted the amido groups to carboxyl groups. The reaction was stopped by neutralizing the latex with dilute hydrochloric acid. Then the latex was, in turn, dialyzed, centrifuged, decanted, and redispersed repeatedly. Depending somewhat on the level of acrylamide present in the original co-polymer, the carboxyl groups tended to be on the particle surface. 

Treatment of a styrene-acrylamide latex similar to the one mentioned immediately above with 0.34 gm of 35% formaldehyde at various pH s for 1 hr at 50 C introduced A/-hydroxymethyl groups on the amido-nitrogens. The highest surface density of 7V-hydroxymethyl groups was obtained when the reaction was mn at pH 12.1. The product work-up was similar to that described above.

The second study concerns polymerisation of various monomers, viz. styrene, acrylamide, and methyl methacrylate, in bicontinuous cubic phases [6.11]. These phases are simultaneously continuous in both the hydrophilic component (water) and the hydrophobic component (hydrocarbons), and they also have a crystallographic cubic symmetry. This is a judicious choice. These phases are extremely viscous and rearrange themselves very slowly compared with bicontinuous microemulsions. The latter have low viscosity and continuously reorganise on a microsecond time scale. 

Synthetic polymers containing sugar branches have attracted considerable interest in recent years. These are typically produced via chemoenzymatic routes where the first step is the enzyme-mediated synthesis of the sugar ester monomer followed by chemical polymerization (Scheme 2). Several workers have developed sugar ester-abased polymers containing vinyl, styrene, acrylamide, etc., functionalities. A discussion of the synthesis methods of these compounds are not in the scope of the current work and interested readers are referred to some recent literature by Patil et al. [64], Kitagawa and Tokiwa [65], and Raku and Tokiwa [66]. 

The nanoparticles consist of pyrogenic colloidal SiOj (Aerosol 1380, Degussa Co., Germany) with an average particle size of 7 nm. Styrene, acrylamide, methyl methacrylate, butyl acrylate, ethyl acrylate, methyl acrylic acid, and vinyl acetate, were used as grafting monomers without further purification.
