摘要

4,4 ' - being the bihuenoruporisuruhon composition, 50 mols which were formed at least phosphorus content composition, and bisphenol A of 1 which 0.01 mass % is more 50 mols which were formed as a main component, 4,4 ' - bihuenoru and at least by the reaction with the sulfonic monomer SM of 1 kinds₁ % at least the polysulfone of 1 where it includes a more repetitive unit kinds (B ^ol PSU), on the basis of all mass of the aforementioned composition, is selected from organic hosuhuitsuto or the organic phospho knight kinds and by the reaction with the sulfonic monomer SM of 1 kinds₂ at least % at least the polysulfone of 1 where it possesses a more repetitive unit kinds (B ^ol A PSU) the composition which is included. 4,4 ' - the bihuenoruporisuruhon composition 60 mass % includes B ^olPSU at least on the basis of the all mass, the 410C, 50 seconds ^-1 (VR₄₀) at slipping speed, possesses the melt viscosity ratio of 1.20 or less. The method especially of being appropriate in order to manufacture the above-mentioned composition. The goods which are manufactured are made from the above-mentioned composition and or by the above-mentioned method.
