Preparation of a high molecular weight polypentafluorostyrene (PFS) and sulfonated polypentafluorostyrene (sPFS) is described in this paper. The high molecular weight PFS was obtained via classical emulsion polymerization reaction, which increased the molecular weight of PFS of about one order of magnitude higher than the one of the commercial polymer. The molecular weight is a crucial factor for...
In this contribution novel acid–base polymer blend membranes are introduced. The membranes are composed of sulfonated poly(etheretherketone) sPEEK Victrex or poly(ethersulfone) sPSU Udel® as the acidic compounds, and of PSU Udel® diaminated at the ortho position to the sulfone bridge, or poly(4-vinylpyridine), poly(benzimidazole) PBI CELAZOLE®, or poly(ethyleneimine) PEI (Aldrich) as the basic compounds...
