Controlled synthesis of sulfonated block copolymers having thermoresponsive property by RAFT polymerization of vinyl sulfonate esters

Synthesis of sulfur-containing alternating copolymers by RAFT copolymerization of phenyl vinyl sulfides

“…Controlled radical polymerizations of sulfur-containing vinyl monomers, such as pyridyl disulfide ethyl methacrylate [17][18][19][20], disulfide-based di(meth)acrylates [21][22][23][24], and vinyl monomers with protected thiol groups [25][26][27][28], have been employed in the production of a variety of functional polymers with well-defined structures and highly ordered architectures. Recently, we have also explored the controlled synthesis of sulfurcontaining polymers by reversible addition-fragmentation chain transfer (RAFT) polymerization of S-vinyl sulfonate esters [29,30] and S-vinyl sulfides [31][32][33], which belong to the family of S-vinyl monomers. Indeed, the RAFT polymerization of phenyl vinyl sulfide (PVS) and its derivatives has been successfully used to synthesize well-defined homopolymers and block copolymers with pendant thioether groups [31].…”

Water Control with Gels Based on Synthetic Polymers under Extreme Conditions in Oil Wells

“…As the temperature increases, the thermosensitive blocks tend to self-aggregate, exhibiting enhanced viscosity, which gives them greater stability to the effect of temperature and salinity of the medium [166]. These polymers are characterized by having AM units in the backbone and contain side-hydrophobic groups, including N-allyl benzamide, vinyl naphthalene, divinyl sulfone, oleic imidazoline, and perfluorinated chains along the polymer chain; these units have been shown to be hydrophobic [167][168][169]. The main thermoviscosifying polymers for oilfield application are N-alkyl-substituted AM copolymers, grafted polyethers, and cellulose derivatives [170].…”

“…This is imperative because a predominantly weak associative effect would not necessarily guarantee the needed rheological impact in terms of recovery efficiency even if polymer injectivity is not affected.
