| titleOfInvention | Polyarylene ether sulfones |
| 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-Ar 1 -SO 2 -[Ar 2 -(T-Ar 3 )n-SO 2 ] m -Ar 4 -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 Ar 1 , Ar 2 , Ar 3 and Ar 4 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. |
