example 18

[0199] Example 18: 4,4'-dichlorodiphenyl sulfone (DCDPS) as dihalogen (B Cl B Cl ) of the "Halex" reaction provides a mixture of Halex products

[0200] A 50 ml round bottom flask was charged with 1.0 g (3.484 mmol) DCDPS and 2.1 g (13.94 mmol) CsF and 3.54 g sulfolane and heated to 210°C using an oil bath. The Hallex reaction was carried out at this temperature for 24 hours. After completion of the reaction, a small sample of the reaction mixture was diluted with dichloromethane and treated with activated charcoal to remove color bodies and the dichloromethane solution was removed by rotary evaporator. The residual product was analyzed by GC. GC analysis of the isolated product showed 90.8% DFDPS, 6.7% 4-chloro-4'-fluoro-diphenylsulfone and 2.5% DCDPS starting material.

example 19

[0201] Example 19: 4,4'-dichlorodiphenyl sulfone (DCDPS) as dihalogen (B Cl B Cl ) of the "Halex" reaction provides a mixture of Halex products

[0202]A 50 ml round bottom flask was charged with 2.0 g (6.96 mmol) DCDPS and 2.1 g (13.94 mmol) CsF and 5.0 g sulfolane and heated to 210°C using an oil bath. The Hallex reaction was carried out at this temperature for 24 hours. After completion of the reaction, a small sample of the reaction mixture was diluted with dichloromethane and treated with activated charcoal to remove color bodies and the dichloromethane solution was removed by rotary evaporator. The residual product was analyzed by GC. GC analysis of the isolated product showed 90.5% DFDPS and 9.5% 4-chloro-4'-fluoro-diphenylsulfone.

example 20

[0203] Example 20: 4,4'-dichlorodiphenyl sulfone (DCDPS) as dihalogen (B Cl B Cl ) "Halex" reaction in the presence of PTC provides a mixture of Hallex products

[0204] A 1 L three-neck round bottom flask equipped with a mechanical stirrer with nitrogen inlet and outlet was charged with 253.33 g (0.8823 mol) of DCDPS, 205.0 g (3.529 mol) of anhydrous KF, 10.86 g (4.411 mmol) of 18-crown -6, and 406 g of sulfolane. The mixture was gradually heated to 210° C. in an oil bath and the reaction was carried out at this temperature for 20 hours. After completion of the reaction, the reaction mixture was filtered through a high pressure filter to remove excess salt and dichloromethane was added to the filtered solution. Then deionized water was added to dichloromethane and the organic layer was separated. Then, the organic layer was washed again with deionized water to remove residual sulfolane. Add some activated charcoal to the collected organic layer to remove the color and ad...

Abstract

A process for the manufacturing of a poly(arylether sulfone)polymer comprising reacting in a solvent mixture comprisng 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, Cl, 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.

Description

[0001] This application claims priority to U.S. Provisional Application No. 61 / 724725, filed November 9, 2012, and European Application No. 12194545.5, filed November 28, 2012, the entire contents of each of these applications being incorporated for all purposes Incorporated herein by reference. field of invention [0002] The present invention relates to novel polyarylene ether sulfones derived from bio-based raw materials, a process for the manufacture of polyarylene ether sulfones of high molecular weight derived from bio-based raw materials, and their use in the manufacture of shaped articles the use of. Background of the invention [0003] The development of renewable bio-based chemicals has the potential to reduce the amount of petroleum consumed in the chemical industry and also open new high value-added markets to agriculture; 1,4:3,6-dianhydrohexitol is one such Examples of chemicals. [0004] Potential industrial applications have generated interest in the produc...
