Acrylamides acrylonitriles

By using this technique acrylamide, acrylonitrile, and methyl acrylate were grafted onto cellulose [20]. In this case, oxidative depolymerization of cellulose also occurs and could yield short-lived intermediates [21]. They [21] reported an electron spin resonance spectroscopy study of the affects of different parameters on the rates of formation and decay of free radicals in microcrystalline cellulose and in purified fibrous cotton cellulose. From the results they obtained, they suggested that ceric ions form a chelate with the cellulose molecule, possibly, through the C2 and C3 hydroxyls of the anhy-droglucose unit. Transfer of electrons from the cellulose molecule to Ce(IV) would follow, leading to its reduction... 

Applications As the basic process of electron transfer at an electrode is a fundamental electrochemical principle, polarography can widely be applied. Polarography can be used to determine electroreductible substances such as monomers, organic peroxides, accelerators and antioxidants in solvent extracts of polymers. Residual amounts of monomers remain in manufactured batches of (co)polymers. For food-packaging applications, it is necessary to ensure that the content of such monomers is below regulated level. Polarography has been used for a variety of monomers (styrene, a-methylstyrene, acrylic acid, acrylamide, acrylonitrile, methylmethacrylate) in... 

Significant improvement in controlled polymerizations of a variety monomers, including styrene, acrylates, acrylamide, acrylonitrile, 1,3-dienes, and maleic anhydride has been achieved when alkoxyamines have been used as initiators for living, free radical polymerization.(696c, 697) Alkoxyamines can be easily synthesized in situ by the double addition of free radicals, generated by thermal decomposition of an azo-initiator, such as 2,2 -azo-h/.s-/.so-butyronitrile (AIBN), to nitrones (Scheme 2.206).

Most of the water-soluble monomers, such as the acrylic and methacrylic acids, are functional monomers and are covered in Section 6.2.3. In Table 6.1 the most water-soluble monomers are acrylamide, acrylonitrile, methyl acrylate and vinyl acetate. Acrylamide contains two reactive centres. The amide group undergoes the reactions characteristic to aliphatic amides. For this reason, acrylamide may be considered as a functional monomer. Copolymerization of acrylamide with other monomers is often done to incorporate hydrophilic centres in oleophylic polymers to promote adhesion and dye acceptance. The monomer is available either as a solid or as a 50% aqueous solution. The latter is the preferred form, since it eliminates handling of a solid. The monomer is a neurotoxin and exposure to skin or inhalation must be prevented. Acrylamide solution is stabilized with cupric ions. Cupric ion availability is pH dependent and the pH must be between 5.2 and 6. Storage temperature should be between 16 and 32 °C...
