The synthesis and some properties of polyarylene sulphonoxide-polytetramethyleneoxide block copolymers

Preparation of Polysulfone/Poly(ethylene oxide) Block Copolymers

“…Previously, Butuc et al 2 showed that R-hydroxy-ω-allyl-PEO could be reacted with a chlorophenyl sulfone terminated polysulfone oligomer in a two-step process to form poly(ethylene oxide)-modified polysulfones. In related work, Aksenov et al 3 have previously prepared poly(ethylene oxide)/polysulfone block copolymers. However, they employed diisocyanate chemistry to link hydroxy-terminated polysulfone oligomers and poly-(ethylene glycol).…”
