A telechelic organic–inorganic polymer (SiPPSU) where –SiPh(OH) 2 groups are covalently linked to the polymeric chain of polyphenylsulfone (PPSU) was prepared and characterized. The polymer was sulfonated up to a degree of sulfonation (DS) equal to 2 (SiSPPSU), then used to prepare blends with sulfonated polyetheretherketone (SPEEK) having DS=0.9 in 5 and 10wt.% concentration. The synthesized...
