Definitions

  • sulfinated polymers can be modified in many ways by means of sulfinate-S-alkylation. This reaction can also be used to introduce functional groups into polymers that cannot be introduced using other methods. A selection of the new reactions found is shown in Fig. 1.
  • the first group concerns the reaction of sultons with polymeric sulfinates, as shown for example in Fig. 2.
  • any sulton can be used.
  • the small ring sultons (4- and 5-ring) are more reactive than the large ring sultones (6-ring and larger) due to their high ring tension.
  • the highest reactivities show the perfluorinated small ring sultons like the perfluorinated sulton shown in Fig. 2. Lactams, lactones and sultams as well as mixed compounds from these components can also be reacted with sulfinates.
  • the second group of reactions is the surprisingly possible alkylation of polymeric sulfinates with haloaryl, haloalkyl and halobenzylammonium and phosphonium salts, as shown for example in FIG. 3.
  • ammonium or phosphonium salt is not subject to any restriction, but preference is given to those ammonium or phosphonium salts which either have long alkyl (> propyl) - or the phenyl groups on the ammonium / phosphonium group, since such salts are better in the organic solvents are soluble in which the polymeric sulfinates are also soluble (dipolar aprotic solvents such as N, N-dimethylformamide DMF, N-methylformamide, N, N-dimethylacetamide DMAc, N, N-dimethylpyrrolidinone NMP, dimethylsulfoxide DMSO, sulfolane).

  • the following order of reactivity of the alkylation of the sulfinate group was found for the halogen leaving groups of haloaryl compounds: F »Cl>Br> I.
  • halogen compounds reacting with polymeric sulfinates are, surprisingly, halogenated primary, secondary and tertiary aliphatic, aromatic and / or benzylic amines as well as halobenzyl amines and their hydrohalides, some of which are shown in FIG. 4.
  • the amino groups can also be protected with an amine protecting group.

  • Fig. 4b shows the reaction of haloalkyl imidazoles with polymeric sulfinates.
  • a fourth group of reactions relates to the surprisingly possible S-alkylation of sulfinates with haloalkyl or haloaryl or halobenzyl sulfonates, phosphonates, carboxylates boronates or their nonionic precursors, some of which are shown in Fig. 5a.
  • the nonionic precursors of the sulfonates, phosphonates and carboxylates are preferred because, on the one hand, they dissolve better in the organic solvents, which are also used to dissolve the polymeric sulfinates, and on the other no undesirable interactions with the sulfinate groups (such as the formation of ion pairs).
  • crown ethers can also be added to the polymer sulfinate solutions and the haloaryl-haloalkyl or halobenzyl carboxylates, haloaryl, haloalkyl or halobenzylphosphonates or haloaryl, haloalkyl or halobenzylsulfonates or haloaryl, haloalkyl or halobenzylboronates in order to complex the cations of the salts.
  • the aromatic fluorine compounds react best with sulfinates with S-alkylation. It has surprisingly been found that the addition of calcium compounds to the reaction mixture and / or the aftertreatment of the polymers, polymer blends, polymer (blend) membranes or other moldings from the reaction products according to the invention with aqueous solutions of calcium compounds favors the sulfinate-S-alkylation reaction.
  • Calcium triflate trifluoromethanesulfonic acid calcium salt
  • a calcium salt which is sparingly soluble in the organic solvent used to the reaction mixture, since even the smallest concentrations of calcium and fluoride ions in the reaction mixture are sufficient,. to precipitate calcium fluoride.
  • Calcium mineral salts can also be added to the reaction mixture: calcium halides, calcium sulfate, calcium hydrogen sulfate, calcium phosphates and calcium phosphates, calcium oxide, calcium hydroxide and other calcium salts.
  • Fig. 5b shows the postulated course of the reaction of a polymeric Li sulfinate with pentafluorobenzenesulfonyl chloride.
  • the covalently crosslinked ionomer membranes formed have a surprisingly low ionic resistance with a surprisingly low water absorption (swelling) (see application examples).
  • Ionomer membranes leads to particularly high chemical stability and low swelling even at high temperatures.
  • hetaryl halogen compounds Another, fifth group of substances that surprisingly can react with polymeric sulfinates with S-alkylation are hetaryl halogen compounds, a selection of which is shown in Fig. 6.
  • Fig. 7 shows exemplary reactive groups of dyes that react with sulfinate groups under S-alkylation.
  • the order of the affinity of the (het) aromatic halogen compounds for the S-alkylation reaction is F>Cl>Br> I.
  • the reactive groups are not limited to halogen residues, but can also have masked or unmasked vinyl sulfone groups or other unsaturated olefin groups.
  • olefins which have electron-withdrawing groups (for example sulfone groups, sulfonate groups, sulfonamide groups, sulfonimide groups, nitro groups, halogen groups, nitroso groups, carbonyl groups, carboxyl groups).
  • Fig. 8 shows examples of reactive dyes that react according to the invention.
  • One area of application for polymers colored with reactive dyes in this way is non-linear optics.
  • the advantage of these polymers is that the dyes are permanently bound to the polymer by the alkylation reaction according to the invention. It has also been found, surprisingly, that the method according to the invention can also be used to introduce functional groups into polymers into which these groups cannot normally be introduced.
  • a metalation reaction can be used to introduce a functional group into metallizable polymers that has intrinsic conductivity (Fig. 9) 6 .
  • a group of polymers which can not be metalated are, would then add up at the carbonyl organometallic ⁇ compounds such as n-butyl lithium, the polyether ketones.
  • the method according to the invention opens up. now a way to introduce the intrinsically conductive group into polyether ketones.
  • the sulfochloride groups are reduced to sulfinate groups using, for example, sodium sulfite.
  • the sulfinate groups can then be alkylated with a halogen-containing compound that contains the intrinsically conductive functional group (Fig. 10).
  • alkylation groups F, Cl, Br, I
  • Halobenzyl groups Hal-CH 2 -Ar
  • polymers according to the invention with alkylation groups are, in particular, halogen-methylated polymers (for example chloromethylated polystyrene, bromomethylated polysulfone).
  • membranes or other moldings which contain alkylation groups are swollen in a suitable organic solvent which contains low or high molecular weight sulfinate compounds.
  • the alkylation takes place either superficially or in bulk.
  • covalently crosslinked thin films (membranes) or other molded articles can be produced from polymers by means of sulfinate-S-alkylation in one step by preparing the following reaction mixtures in a first step:
  • a sulfinated polymer is dissolved in a suitable solvent.
  • An alkylating agent or a mixture of various alkylating agents is then used for the solution, the alkylating agent.
