Free-radical copolymerization of methyl methacrylate with styrene in the presence of 2-mercaptoethanol

Kinetics of cotelomerization of 3-(trimethoxysilyl)propyl methacrylate and perfluorodecylacrylate

“…Teodorescu et al also obtained a C T value of 0.62 for methyl methacrylate in benzene at 60°C. [7] Finally acetonitrile was a solvent able to provide an efficacious transfer avoiding strong hydrogen bonds or dipole-dipole interactions between the solvent and the monomer. Moreover acetonitrile is a good solvent for PFDA co-units for further study of copolymerisation of TMSPMA with PFDA.…”

“…Mercaptans have been extensively studied: thioglycolic acid, [1][2][3] 2-mercaptoethylamine, [4] 3-mercaptopropionic acid, [4] and 2-mercaptoethanol. [5][6][7][8] The efficiency of 2-mercaptoethanol in transfer reactions has been outlined and explored in several previous investigations. [6][7] Its reactivity has been well studied in the case of the cotelomerization of methyl methacrylate with styrene in order to obtain α-hydroxyl oligomers with random type copolymer structures for a further utilization as macromonomers.…”

[7] Fluorinated polymers are unique materials since they combine chemical inertness (to acids, bases and solvents), low water absorptivity, excellent weartherability, good resistance to oxidation, aging, and very interesting surface properties with low surface energy.…”

Among the fluorinated monomers, acrylates with long perfluoroalkyl (R f ) side chains, such as perfluorodecylacrylate (PFDA) monomer, offer interesting properties.…”

Free radical polymerization of vinyl acetate in the presence of liquid polysulfides

“…In the last case, ABA triblock copolymers with polysulfide middle block and poly(methyl methacrylate) [10] or poly(methyl methacrylate-co-styrene) [11] side blocks were synthesized by taking advantage of both chain transfer ability in radical processes [12][13][14][15] and chemical oxidation sensitivity [16][17][18] of the mercaptan groups.…”
