Proton conducting ABA triblock copolymers with sulfonated poly(phenylene sulfide sulfone) midblock obtained via copper-free thiol-click chemistry

Abstract

A series of charged ABA triblock copolymers having sulfonated poly(phenylene sulfide sulfone) (sPSS) as B-block and polystyrene (PS) as A-block have been successfully synthesized using copper-free thiol-click chemistry. One-pot sequential...

Recent advances on the structure–properties relationship of multiblock copolymers

“…[38][39][40][41] Lastly, polystyrene (PS) forming amorphous spherical domains in soft PB or PI is used for several decades, [2][3][4][5][6][7][8] and until recently, in association with soft poly(phenylene sulfide sulfone). 42 Note that beyond their chemical nature, their length and their number density, the HSs polymolecularity, their position in the chain and the architecture of the molecule (e.g., comb, stars …) strongly impact the phase diagram of MBCs. [43][44][45][46] The interest of MBCs is multiple.…”

“…47 These materials present the great advantage to be melt processable and possibly reparable on-demand, 48,49 making them promising candidates to substitute vulcanized rubbers in many applications including, but not limited to, wire sheaths, 50 shoe soles, seals and possibly tires. 51,52 Besides, TPEs are frequently used as bitumen modifiers, 53,54 adhesives, 55,56 energy dissipators, 57 reinforcing fibers, 58 ground coverings, polyelectrolytes, 42,59 compatibilizers, 60 strain sensors, 61,62 antibacterial coatings 63 and particularly in the car industry as dashboard elements or other automotive parts. 64,65 On top of this, MBCs progressively become eco-friendly, incorporating biodegradable HSs, 66,67 without significant loss of mechanical properties.…”

“…In this case, the word “ordered” is sometimes used to substitute “crystalline”, 37 revealing the uncertainty regarding the molecular arrangement of these complex molecules 38–41 . Lastly, polystyrene (PS) forming amorphous spherical domains in soft PB or PI is used for several decades, 2–8 and until recently, in association with soft poly(phenylene sulfide sulfone) 42 . Note that beyond their chemical nature, their length and their number density, the HSs polymolecularity, their position in the chain and the architecture of the molecule (e.g., comb, stars …) strongly impact the phase diagram of MBCs 43–46 …”
