Kinetics of copolymerization of methyl methacrylate and divinyl sulfide in the presence of initiating systems

Reversible deactivation radical polymerization of polyfunctional monomers

“…As a result of RDRP in a thermodynamically good solvent [136] and in a thermodynamically poor solvent with an added polymer stabilizer (dispersion polymerization) [34,35,[137][138][139], the following polymer products can be prepared: monodisperse functional microbeads based on methyl methacrylate [140]; narrowly disperse, densely crosslinked, surface functionalized micro beads based on 4 vinylpyridine, glycidyl methacrylate, and 2 hydroxyethyl methacrylate [141]; thermosensi tive nanogels based on a macrodeactivator (poly(N,N' dimethylacrylamide with a trithiocarbon ate group at the chain end), 2 methoxyethyl acrylate, methoxy poly(ethylene glycol acrylate), and poly(eth ylene glycol diacrylate) [142]; biocompatible ther mosensitive nanogels based on methoxy(diethylene glycol methacrylate), methoxy poly(ethylene glycol methacrylate), and poly(ethylene glycol dimethacry late) [143]; microbeads with immobilized surface dithioester groups [144]; water compatible polymer microbeads [145]; Atrazine imprinted polymer microbeads (a capacity up to 2.89 mg/g) based on methacrylic acid and 4 vinylpyridine [146]; diben zothiophene imprinted (a capacity up to 2.89 mg/g) silica gel particles modified by methacrylic acid and 4 vinylpyridine copolymers [147]; Cefalexin imprinted (a capacity up to 59.4 mg/g) thermosensi tive polymer shell of yeast based on N isopropylacryl amide and ethylene glycol dimethacrylate [148]; 2,4 dichlorophenoxyacetic acid-and phenoxyacetic acid-imprinted polymer microbeads made from N isopropylacrylamide [149]; lysozyme imprinted thermosensitive spherical nanogels of N isopropyl acrylamide [150]; and polymer microbeads based on styrene, methyl methacrylate, and divinylsulfide [22,151].…”

“…It was first stated that the product of this reaction is a three dimensional molecule, and the reaction received the name three dimensional radical polymerization [2][3][4][5][6][7][8][9]. This is the term that is most frequently used in the Russian liter ature [10][11][12][13][14][15][16][17][18][19][20][21][22], whereas outside Russia, apart from three dimensional polymerization, different terminol ogy is used-crosslinking polymerization [23][24][25][26][27], branching polymerization [28,29], network polymeriza tion [30], etc.-depending on the process conditions and the structures of the resulting polymers. In spite of the versatile conditions of performing three dimen sional radical polymerization that result in a wide vari ety of polymer materials strongly differing in proper ties (polymer networks, branched polymers, micro and nanogels) [13,[31][32][33][34][35], from the chemical point of view, the same process is used.…”
