Document Type and Number:
WIPO Patent Application WO/2014/072473
Kind Code:
A3
Abstract:
A process for the manufacturing of a poly(arylether sulfone) polymer comprising reacting in a solvent mixture comprising a polar aprotic solvent and in the presence of an alkali metal carbonate, a monomer mixture which contains : at least one 1,4:3,6-dianhydrohexitol selected from the group consisting of isosorbide (1), isomannide (2) and isoidide (3); at least one dihaloaryl compound of formula (S) : X-Ar1-SO2-[Ar2-(T-Ar3)n-SO2]m-Ar4-X wherein n and m, equal to or different from each other, are independently zero or an integer of 1 to 5; X and X', equal to or different from each other, are halogens selected from F, C1, Br, I; each of Ar1, Ar2, Ar3 and Ar4 equal to or different from each other and at each occurrence, is an aromatic moiety, T is a bond or a divalent group optionally comprising one or more than one heteroatom; optionally, at least one dihydroxyl compound different from the diol (AA); optionally, at least one dihaloaryl compound different from the dihalo (BB); and optionally, at least one hydroxyl-halo compound [hydro-halo (A'B')]; being understood that the overall amount of halo-groups and hydroxyl-groups of the monomers of the monomer mixture is substantially equimolecular, so as to obtain a polymer (b-PAES), wherein the reaction is carried out at a total % monomer mixture concentration equal to or more 10 % and less than 70 % with respect to the combined weight of monomer mixture and solvent mixture.
