External magnetic field effect on the dye-photoinitiated polymerization of acrylamide

Magnetic field effects on the free radical solution polymerization of acrylamide

“…Moreover, MF effects were most pronounced for polymerizations carried out in viscous polar media. In particular, the solution photopolymerization of acrylamide (AM) in binary mixtures of water/ethylene glycol (EG) has shown increased R p [8]. Similar results were obtained for the photopolymerization of AM in water and water/methanol mixtures [6].…”

“…Moreover, several authors published a values only slightly different from unity: 1.00 [26,27], 1.04 [28], 1.07 [29], 1.10 [30], and 1.16 [31]. Various amounts of EG were mixed with water to vary the viscosity of the reaction medium but maintaining good solvation properties for the reactants and the reaction products [8].…”

Politiyofen/PEDOT Kompozitinin Termoelektrik Özelliklerine Sıvı Kristal ve Manyetik Alanın Etkisi

“…Diğer taraftan, manyetik alan (MA) altında sentezlenen geleneksel polimerlerin, geleneksel yöntemlerle sentezlenenlere kıyasla farklı özellikler ve kinetikler sergiledikleri bildirilmiştir [21]. MA, diamanyetik özellikleri olan bileşiklerin kimyasal reaksiyonlarının entropisini etkiler [22][23][24]. Diyamanyetikten paramanyetik hallere dönüştüğünde, kimyasal reaksiyonların MA ile hızlandırılabileceği önerilmiştir [25].…”

Radical Homo‐ and Copolymerization of Acrylamide and Ionic Monomers in Weak Magnetic Field

“…MF effects have previously been observed for the radical homopolymerization of styrene, [2][3][4][5][6][7][8][9] methyl methacrylate, [10][11][12][13][14][15] and acrylamide. [16][17][18] In general, MF was found to increase the monomer consumption rate (Rp), and sometimes the molar masses of resulting polymers. A MF-induced increase of the efficiency of photoinitiators (F) and induced decrease of the rate of termination reactions have been proposed as mechanistic explanation.…”
