Definitions
- the present invention relates to a novel production process for polyimides. STATE OF THE ART
- Polyimides are valuable materials for various applications. Their synthesis is usually carried out by polycondensation of diamines with dianhydrides in solution, in the melt or even in a solid state. Surprisingly, it was found several years ago that - despite the elimination of water during the condensation reaction - even water can be used as a solvent for the polyimide synthesis, when so-called “hydrothermal conditions” prevail, to understand a reaction under pressure at temperatures above 100 ° C. (see Hodgkin et al., "Water as a Polymerization Solvent-cyclization of Polyimides: Le Chatelier Confounded", Polym. Prep. (American Chemical Society, Division of Polymer Chemistry) 41, 208 (2000), and WO 99 / 06470). When solvents other than water are used, the term “solvothermal conditions” is used at temperatures above their boiling points.
- Dao et al. (Dao, Groth and Hodgkin, "Microwave-assisted aqueous polyimidization using high-throughput Techniques ", Macromol, Rapid Commun., 28, 604-607 (2007);” Dao 2007 ”) by means of serial experiments with a ternary monomer mixture of a diamine (4,4-oxydi- aniline, ODA) and two dianhydrides (4,4 ').
- AH salts it is first from previously dehydrated polyamines and polyanhydrides in the presence of a defined proportion of, for example, 5 to 60 mol% of monoanhydrides as terminators prepolymers, ie low molecular weight oligomers, prepared from which in the sequence Suspensions or - after grinding them to obtain smaller particle sizes - colloidal solutions are formed in water, which are used for coating surfaces.
- monoanhydrides as terminators prepolymers, ie low molecular weight oligomers, prepared from which in the sequence Suspensions or - after grinding them to obtain smaller particle sizes - colloidal solutions are formed in water, which are used for coating surfaces.
- suspension stabilizers it is also preferable to add suspension stabilizers to the prepolymers obtained, which are characterized as being insoluble in water.
- the present invention solves this problem by providing a process for the preparation of polyimides by polycondensation of stoichiometric salts of polycarboxylic acids or their polyanhydrides and polyamines previously prepared by heating the salts for dehydration, which is characterized in that
- This invention is based on the inventors' most surprising finding that some monomer salts of polycarboxylic acid and polyamide are water-soluble, and thus do not precipitate upon mixing of the monomers from an aqueous solution, in contrast to all other known such salts. Due to this unique property, it is possible to subject such an aqueous solution of the monomer salts directly to a processing step and simultaneously or sequentially by heating - preferably to a temperature Tp which is above the solid state polymerization temperature of the salt to complete conversion of the To ensure polycondensation reaction - to undergo a polycondensation.
- the aqueous solution is applied to a support or a substrate to obtain a coating and the resulting coating is polycondensed by heating.
- the coating is preferably dried before the polycondensation in step c), whereby a film or a solid film is formed on the substrate, which is easier to handle than the moist coating.
- the aqueous solution is foamed in processing step b), after which the resulting foam is cured by polycondensation in subsequent step c) to obtain a cured polyimide foam.
- the aqueous solution is fed to a nozzle heated to a temperature above Tp, where the stoichiometric salt in step c) is simultaneously cured by polycondensation and the resulting polyimide is forced through the nozzle opening (s), to obtain a molded polyimide product.
- the polyimide thus obtained can be wet-spun, press-molded or extruded into filaments, for example, depending on the particular nozzle used and the associated molding apparatus. Wet-spun filaments are then preferably wound on spools to obtain polyimide fibers.
- the water-soluble stoichiometric salt is preferably prepared in step a) by mixing stoichiometric amounts of polycarboxylic acid or its polyanhydride and polyamine in water or in an aqueous solvent mixture. Furthermore, the water-soluble stoichiometric salt is preferably precipitated by adding at least one organic solvent for intermediate storage prior to the polycondensation.
- the organic solvent used therefor is not particularly limited so long as it sufficiently lowers the solubility of the stoichiometric salt in the formed aqueous solvent mixture to cause precipitation thereof, provided that it is itself a nonsolvent for the stoichiometric salt.
- Both water-miscible and water-immiscible solvents can be used for this purpose, for example alcohols, e.g. such as methanol or other lower alcohols, ethers, e.g. THF, acetone, etc.
- a film is drawn from the aqueous solution of the water-soluble stoichiometric salt on a substrate so as to optionally follow the subsequent polycondensation of the salt to the corresponding polyimide a composite material or, after peeling the cured polyimide film from the substrate, to obtain a polyimide film.
- a water-soluble stoichiometric salt of a tetracarboxylic acid and a diamine is prepared and polycondensed, since these are the most common starting materials in polyimide production.
- polyhydric amines and / or polycarboxylic acids or their anhydrides are also possible, e.g. the preparation of stoichiometric salts of triamine and dianhydride, diamine and trianhydride, triamine and trianhydride, etc. as long as these monomers form water-soluble salts in the corresponding stoichiometric composition.
- the tetracarboxylic acid is particularly preferably selected from benzophenone tetracarboxylic acid, tetrahydrofurantetracarboxylic acid, butanetetracarboxylic acid and their dianhydrides, since the inventors have already found water-soluble stoichiometric salts of these polycarboxylic acids.
- the diamine is preferably selected from benzenedimethanamine and ethylenediamine.
- the present invention also provides these specific compounds, namely 1,3-Benzenedimethanammonium dihydrogen-3,3 ', 4,4'-benzophenone tetracarboxylate (1):
- the present invention also provides two novel polyimides synthesized and characterized for the first time by the inventors - from the corresponding water-soluble stoichiometric salts (3) and (5), namely:
- Figs. 1 to 5 are IR spectra of the water-soluble stoichiometric monomer salts obtained in Examples 1, 4, 6, 7 and 8 and Figs Figures 6 and 7 show IR spectra of the polyimides obtained in Examples 12 and 13.
- Example 1 The batch of Example 1 was repeated, to which 30 ml of THF were added to the resulting aqueous solution of (1) (here: in 5 ml of distilled water), a precipitate forming in the form of a white turbidity. The mixture was allowed to stand overnight, with the initial precipitate turning yellow formed second liquid phase, which was crystallized after a further 24 hours rest to colorless crystals.
- Example 1 was repeated, using instead of the isolation of the stoichiometric salt (1) by evaporation of the water, the aqueous solution for coating a glass plate. For this purpose, a few drops of the solution were dropped on a glass plate and allowed to air dry. Subsequently, the polycondensation to poly (N, N '- (benzene-1, 3-dimethylene) benzophenone-3,3', 4,4'-tetracarboxylic diimide) was carried out in a vacuum oven maintained at 200 ° C overnight. The IR spectrum of the polyimide thus obtained corresponded to that of the product known from the literature.
- Example 4 The batch of Example 4 was repeated, to which 30 ml of THF were added to the resulting aqueous solution of (2) (here: in 5 ml of distilled water), a precipitate forming in the form of a white turbidity. The mixture was allowed to stand overnight, with the initial precipitate forming a yellow colored second liquid phase, which crystallized after a further 24 hours rest to colorless crystals.
- Example 1 The batches of Examples 1, 4, 6, 7 and 8 were repeated, using the aqueous solutions for coating glass plates, similar to Example 3, instead of isolating the stoichiometric salts.
- 5 to 10 ml of the respective aqueous solution were applied to a glass plate, which was then in an oven at a heating rate of 5 K / min was heated to 250 ° C and then maintained at this temperature for 30 min.
- Example 10 Poly (N, N '- (benzene-1,3-dimethylene) benzophenone-3,3', 4,4'-tetracarboxylic diimide); in Example 10 (with the stoichiometric salt obtained analogously to Example 4): poly (N, N '- (benzene-1,3-dimethylene) butane-1,2,3,4-tetracarboxylic acid diimide) and in Example 1 ( with the stoichiometric salt obtained analogously to Example 7): poly (N, N '- (1, 2-ethylene) benzophenone-3,3', 4,4'-tetracarboxylic acid diimide);
- Example 12 (with the stoichiometric salt obtained analogously to Example 6): poly (N, N '- (benzene-1,3-dimethylene) tetrahydrofuran-2,3,4,5-tetracarboxylic diimide) (6); and in Example 13 (with the stoichiometric salt obtained analogously to Example 8): poly (N, N '- (1,2-ethylene) tetrahydrofuran-2,3,4,5-tetracarboxylic diimide) (7).
- the present invention thus provides a process by which polyimide coatings can be prepared from aqueous solutions of the stoichiometric monomer salts, which is a considerable advantage over the prior art, as it limits the use of expensive and only with enormous energy expense to be removed solvent or even avoided altogether.
- the invention should not be limited to the five monomer combinations disclosed herein, especially since the person skilled in the art - who now has the knowledge that such water-soluble monomer salts actually exist - is easily able to do so by simple routine experiments, including other combinations of polycarboxylic acid or Polyanhydride and polyamines, which give a water-soluble stoichiometric salt.
