Anionic hydrogen‐transfer polymerization of N‐isopropylacrylamide under microwave irradiation

Abstract: Anionic hydrogen‐transfer homopolymerization of N‐isopropylacrylamide (NIPAAm) was carried out using t‐BuOK as an initiator in DMF under microwave irradiation. After 100 W of microwave was irradiated to the reaction mixture at 140°C for 6 h in the temperature control mode, corresponding polymer was obtained in 10% yield. In the case of conventional oil bath heating, by contrast, corresponding polymer was not obtained in similar anionic polymerization conditions. With 100 W and 2.45 GHz of microwave irradiation… Show more

“…Microwaves are electromagnetic waves characterized by frequency in the range of 300 MHz to 300 GHz [ 38 ] and have long been used for polymerization reactions [ 48 ], for the synthesis of an extensive range of polymers [ 49 ], for the development of hydrogel scaffolds [ 50 ], for the fabrication of hydrogel [ 51 ] and nanoparticle gel [ 52 ], for improving the mechanical properties of the polymer [ 53 ], for polymer modification and composite film formulation [ 54 , 55 ], and for polymeric films [ 56 , 57 ]. Microwave interacts with polar functional groups in a volumetric manner, thereby initiating polymer cross-linking through their polar moieties, with the added merits of excluding the use of catalysts or additives to start the reaction and simplicity of irradiation methods; the crosslinking point may be controlled effortlessly by differing the dose of irradiation [ 36 ].…”

“…Hydrogen transfer polymerization (HTP) is a useful route that can insert functional groups into the backbone of a macromolecule. However, it is necessary to use a monomer with a loose proton(s) and vinyl group to obtain the product via HTP (Çatıker et al 2018;Iwamura et al 2019). Free-radical polymerization (FRP) is a wellknown polymerization technique and is broadly used today.…”
