Novel Sulfonated Poly(arylene ether sulfone)s: Preparation and Properties

Poly(arylene ether sulfone)s (PESs) are known for their excellent thermal and mechanical properties. Two series of novel poly(arylene ether sulfone)s were prepared using direct copolymerization of 3,3 -disulfonated- 4,4 -dichlorodiphenyl sulfone as synthesized sulfonated dihalide in companion with 4,4 -dichlorodiphenyl sulfone as nonsulfonated dihalide monomer with hydroquinone or 4,4 -(4,4 -sulfonylbis-(1,4-phenylene)bis(oxy))diphenol) as diol. Copolymers were synthesized with controlled degrees of sulfonation (40, 50 %). 1H-NMR and FT-IR spectroscopy were used for characterization of prepared polymers. Dynamic mechanical thermal analysis and thermogravimetric analysis were applied for investigation and comparison of their properties. The polymers showed potential applications as membrane of fuel cell
