How does ceric ammonium nitrate polymerize acrylamide?
Ceric ammonium nitrate (CAN) is one of the most studied chemicals, as it can efficiently induce a radical on the polysaccharide which can initiate the polymerization of the vinyl monomer [ 185 ]. The mechanism of polymerization is described on Figure 4. Mechanism of polymerization of acrylamide using Ce4+/alcohol redox system.
Does polyacrylamide depolymerize on acrylamide monomer?
Indeed, King et al. and Smith et al. confirmed the innocuity of polyacrylamide, whereas acrylamide monomer is classified as neurotoxic. In another study led on polyacrylamide used in agriculture, Anh et al. showed that polyacrylamide does not depolymerize on toxic acrylamide monomer, despite a misleading title [ 121 ].
Does T-Buona initiate bulk hydrogen-transfer polymerization of acrylamide?
Mechanistic insights into bulk hydrogen-transfer polymerization of acrylamide initiated by t -BuONa are proposed in this study where attention is particularly given to the initiation and propagation steps. This anionic polymerization methodology led to the synthesis of polyamide-3 with controlled molar masses.
Are acrylamide polymers more active or less active?
Indeed, monomers can be classified as more active monomers (MAMs), such as acrylamide or acrylates, and less active monomers (LAMs), such as N -vinylpyrrolidone or methacrylate. When considering acrylamide polymerization, the large amount of heat released (82.8 kJ·mol −1) results in a fast temperature rise [ 65 ].
