Definitions
- the present invention relates to aqueous dispersions of fluoropolymers which are essentially free of fluorine-containing emulsifiers, a process for the preparation of such dispersions and their use.
- “Substantially free” means a content of less than 100 ppm, preferably less than 50 ppm, particularly preferably less than 25 ppm and in particular less than 5 ppm.
- Polyfluoroethylene dispersions are widely used in the coating industry because the coatings are unique in terms of application technology
- non-stick properties such as non-stick properties, good weather resistance and non-flammability. They are mainly used to coat kitchen appliances, chemical equipment and glass fabrics. In many such applications, the dispersions are applied with relatively high solids contents, for example up to 70% by weight. These concentrated dispersions are mainly colloidally stabilized with nonionic emulsifiers, such as, for example, alkylaryl polyethoxy alcohols and alkyl polyethoxy alcohols.
- aqueous emulsion polymerization firstly leads to homopolymers which cannot be processed from the melt, for example PTFE, secondly to "modified” polymers, for example a polymer with more than about 99 mol% of tetrafluoroethylene (TFE) and only such a small amount to comonomer (s) that the product retains its character as "not processable from the melt”, thirdly to low molecular weight "micropowder” dispersions which can be processed from the melt, and fourthly to copolymers such as fluorothermoplastics or fluoroelastomers .
- TFE tetrafluoroethylene
- the fluorothermoplastics include copolymers which consist predominantly of TFE and such an amount of one or more comonomers, for example 1 to 50, preferably 1 to 10, mol% that the product can be processed from the melt.
- conventional fluoromonomers are vinylidene fluoride (VDF), other fluorinated olefins, such as, for example, chlorotrifluoroethylene (CTFE), in particular perfluorinated olefins having 2 to 8 carbon atoms, for example hexafluoropropene (HFP), fluorinated ethers, in particular perfluorinated vinylalkyl ether with alkyl parts having 1 up to 6 carbon atoms, for example perfluoro (n-propyl vinyl) ether (PPVE).
- VDF vinylidene fluoride
- CTFE chlorotrifluoroethylene
- HFP hexafluoropropene
- fluorinated ethers in particular perfluorinated vinyl
- Non-fluorinated olefins for example ethylene and propylene
- the dispersions of polymers thus obtained which can be processed from the melt or cannot be processed from the melt, generally have a solids content of 15 to 30% by weight. Therefore, to achieve the above-mentioned high solids content for use as a coating and advantageously also for storage and transportation, the solids content must be increased by concentration.
- thermal concentration according to US Pat. No. 3,316,201, decanting (US Pat. No. 3,037,953) and ultrafiltration (US Pat. No. 4,369,266) are used.
- the known emulsion polymerization usually takes place in a pressure range from 5 to 30 bar and a temperature range from 5 to 100 ° C., as described for example in EP-B 30 663.
- the polymerization process for the production of PTFE dispersions corresponds essentially to the known process for the production of fine resin powders, so-called paste goods (US Pat. No. 3,142,665).
- the polymerization process for the production of copolymers, such as fluorothermoplastic dispersions corresponds to the process for the production of these materials in the form of melt pellets.
- emulsifiers that do not interfere with the polymerization through chain transfer.
- These emulsifiers are called non-telogen emulsifiers (US Pat. No. 2,559,752).
- PFOS perfluorooctanoic acids
- n-PFOS CAS No. 335-67-1
- other fluorinated emulsifiers should not be excluded.
- the content of this emulsifier is generally in the range from 0.02 to 1% by weight, based on the polymer.
- EP-A 822 175 describes the use of salts of CH 2 -containing fluorocarboxylic acids for the emulsion polymerization of TFE.
- WO-A 97/08214 describes the use of 2-perfluorohexylethanesulfonic acid or its salts for the TFE polymerization.
- US Pat. No. 2,559,752 describes further fluorinated emulsifiers which, however, have not been widely used because of their low volatility. These chemicals can discolor the end products at high processing temperatures.
- PFOS Planar metal oxide
- PFOS a very effective emulsifier and practically indispensable due to its inertness during the polymerization.
- PFOS is not biodegradable and has recently been classified as environmentally hazardous.
- the PFOS remains largely in the polymer dispersion, even with ultrafiltration and decanting with a 100-fold excess of the nonionic emulsifier.
- PFOS and its ammonium salt are highly volatile.
- PFOS and its salts are decomposed at the normally used sintering temperatures of 350 to 450 ° C by decarboxylation to fluorocarbons, which have a large warming potential for the climate ("greenhouse effect").
- the present invention provides high solids dispersions that are essentially PFOS free.
- “essentially free” is to be understood as a content of less than 100 ppm, preferably less than 50 ppm, particularly preferably less than 25 ppm and in particular less than 5 ppm. These values refer not only to the solids content, but to the entire dispersion. This is achieved through
- fluorinated emulsifiers for example PFOS
- fluoropolymer dispersions such as for example PTFE, fluorothermoplastic or fluoroelastomer dispersions
- anion exchange namely by adding a nonionic emulsifier to the fluoropolymer dispersion and bringing this stabilized dispersion into contact with a basic anion exchanger.
- This process works without blocking or clogging the ion exchange bed by coagulated latex particles.
- the dispersion obtained can optionally be concentrated.
- Suitable fluoropolymer dispersions in the context of the present invention are dispersions of homopolymers and copolymers of one or more fluorinated monomers, such as TFE, VDF or CTFE or other fluorinated olefins with 2 to 8 carbon atoms, perfluorinated olefins with 2 to 8 carbon atoms, such as HFP, fluorinated ethers, in particular perfluorinated vinyl alkyl ethers with alkyl parts with 1 to 6 carbon atoms, such as perfluoro ( n-propyl vinyl) ether and
- fluorinated monomers such as TFE, VDF or CTFE or other fluorinated olefins with 2 to 8 carbon atoms, perfluorinated olefins with 2 to 8 carbon atoms, such as HFP, fluorinated ethers, in particular perfluorinated vinyl alkyl ethers with alkyl parts with 1 to 6 carbon atoms, such
- Non-fluorinated olefins for example ethylene and propylene, are also suitable as comonomers.
- the invention is intended to include such dispersions regardless of whether the fluoropolymer obtained can be processed from the melt or not.
- the latex particles generally have a submicroscopic diameter of less than 400 nm and preferably from 40 to 400 nm. Smaller particle sizes can be obtained with the so-called "microemulsion polymerization".
- the latex particles are anionically stabilized in a colloidal chemical sense.
- the anionic stabilization is brought about by anionic end groups, mostly COOH groups, and by the anionic emulsifier, such as, for example, PFOS.
- anionically stabilized dispersions coagulate rapidly in an anion exchange bed and thus block the ion exchange bed. This is due to the breakdown of the electrical double layer at the ion exchange centers. Therefore, the treatment of an anionically stabilized dispersion with an anion exchanger, in particular for higher concentrations, is not considered to be technically expedient.
- the impairment or blockage of the ion exchange bed is already observed at concentrations which are 1/1000 of the raw polymer dispersions, that is to say the dispersion after the polymerization.
- concentrations which are 1/1000 of the raw polymer dispersions, that is to say the dispersion after the polymerization.
- the pKa of the acid corresponding to the counterion of the anion exchanger must be higher than the pKa of the anionic end groups of the polymer.
- the anion exchanger preferably has a counterion corresponding to an acid with a pKa value of at least 3.
- the anion exchange is initially carried out in an essentially basic environment.
- the ion exchange resin is preferably converted into the OH " form, but anions corresponding to weak acids, such as fluoride or oxalate, are also suitable. These anions are generally present in the dispersion and originate from the polymerization formulation.
- the specific basicity of the anion exchanger used is not critical. Strongly basic resins are preferred due to the observed higher efficiency in the separation of PFOS.
- the effective separation of PFOS from the dispersions depends on the ion exchange conditions. PFOS breaks through earlier with weakly basic ion exchange resins. The same applies to higher flow rates.
- the flow rate is not critical, standard flow rates can be used.
- the flow can be upward or downward.
- the ion exchange can also be carried out batchwise by gently stirring the dispersion with the ion exchange resin in a container.
- the dispersion is then filtered off.
- the coagulation is reduced to a minimum in a discontinuous mode of operation.
- Nonionic emulsifiers are described in detail in Nonionic Surfactants, M.J. Schick (Editor), Marcel Dekker, Inc., New York 1967.
- nonionic emulsifier is also not critical. Alkylaryl polyethoxy alcohols, alkyl polyethoxy alcohols or any other nonionic emulsifier are suitable for this. This is a great advantage since the formulation of the dispersions used remains essentially unchanged when separating PFOS from commercially available dispersions.
- the PFOS separation is preferably carried out using crude dispersions from the polymerization.
- Such dispersions which generally have a solids content of 15 to 30% by weight, are added with such a large amount of nonionic emulsifier that the dispersion is stable during the subsequent processing, for example the concentration.
- An amount of nonionic emulsifier from 0.5 to 15% by weight and preferably from 1 to 5% by weight is generally sufficient for this.
- the dispersions can be concentrated using customary methods, for example by ultrafiltration or thermal concentration.
- concentration of the nonionic emulsifier in the end product is not much higher than in comparable commercial products.
- the absence of PFOS in these processes does not affect the concentration, that is to say no more coagulum is formed during thermal concentration and ultrafiltration than in the presence of PFOS.
- PFOS by means of anion exchange can also be carried out with already concentrated dispersions with a solids content of up to 70% by weight. Because of the higher viscosity and density of such dispersions, however, this process is technically more complex.
- the ion exchange is preferably operated in the upflow mode to avoid difficulties due to the floating of the
- the high viscosity usually does not allow high flow rates.
- the discontinuous procedure appears to be more advantageous for such high-solids dispersions.
- 1-5% by weight of nonionic emulsifier is generally added to the dispersion with gentle stirring, and it is passed over the anion exchanger.
- the anion exchanger can be pretreated with a solution of nonionic emulsifier, such as is used in the dispersion to be subjected to the exchange.
- the anion exchange resin is preferably brought into the OH " form. For this purpose, the anion exchange resin is brought into contact with a NaOH solution.
- dispersions without adjusting the pH are used for ion exchange, but the pH can also be increased by adding a base such as aqueous ammonia or sodium hydroxide solution to improve the colloidal stability of the dispersion.
- a base such as aqueous ammonia or sodium hydroxide solution
- a pH in the range of 7 to 9 is sufficient.
- the increased pH does not have a major influence on the efficiency of the PFOS separation. This is believed to be due to the fact that the PFOS is not only exchanged but also strongly absorbed on the ion exchange resin.
- the ion-exchanged dispersions are then concentrated, preferably by thermal concentration or ultrafiltration. No impairment of these procedures was found. In addition, the end user processing and the end use properties for such dispersions according to the invention remain unchanged.
- Emulsifier without blocking the ion exchange bed can be successfully used to separate any other anionic emulsifier used in any polymerization process.
- the process in question also applies to all fluoropolymer raw dispersions, such as dispersions of PFA, FEP, THV (THV is a terpolymer of TFE, HFP and VDF), ET (ET is a copolymer of TFE and ethylene), TFE / P (a copolymer of TFE and propylene), copolymers of VDF and HFP and homopolymers or copolymers containing other fluorinated olefins or vinyl ethers.
- THV is a terpolymer of TFE, HFP and VDF
- ET is a copolymer of TFE and ethylene
- TFE / P a copolymer of TFE and propylene
- copolymers of VDF and HFP and homopolymers or copolymers containing other fluorinated
- the quantitative determination of the PFOS content of the dispersion subjected to anion exchange can be carried out according to the method according to "Encyclopedia of Industrial Chemistry Analysis", Volume 1, pages 339 to 340, Interscience Publishers, New York, NY, 1971, and EP-A 194 690 .
- the PFOS is converted into the methyl ester and the ester content is analyzed by gas chromatography using an internal standard.
- the detection limit for PFOS is 5 ppm. This method was used in the following examples.
- AMBERLITE TM IRA 402 with a capacity of 1.2 meg / ml was used as the strongly basic anion exchange resin (AMBERLITE is a trademark of Rohm & Haas).
- the bed volume was usually 400 ml.
- the ion exchanger was included
- NIS 1 octylphenoxypolyethoxyethanol (commercial product TRITON TM X 100, TRITON is a trademark of Union Carbide Corp.).
- NIS 2 Ethoxylate of a long-chain alcohol (commercial product GENAPOL TM X 080, GENAPOL is a trademark of Hoechst AG).
- Anion exchange resin with an aqueous solution of the nonionic surfactant was changed in accordance with Table 1.
- the fluoropolymer dispersion was obtained by homopolymerizing TFE according to EP-B 30 663.
- the solids content of the raw dispersion used is about 20% and the average particle size is about 200 to
- the PFOS content of the dispersion is about 0.13% by weight
- Example 3 shows that 54 ml of the total volume of 400 ml of ion exchange resin is consumed. Thus, the ion exchange capacity provided was more than a 5-fold excess for all examples.
- a raw PFA dispersion was cleaned analogously to Examples 1 to 7. 400 ml of AMBERLITE IRA 402 (OH ' form, pretreated with a 1% solution of NIS 2) were used. The PFA dispersion (1500 ml, solids content 20%) was stabilized with 5% NIS 2, based on the solids content of the dispersion. This dispersion contained 0.066% PFOS and had a pH of 4. The dispersion was at a flow rate of 100 ml / h over the
- Example 9 was carried out with a raw FEP dispersion stabilized with 5% by weight of NIS 2 (solids content 20%, PFOS content 0.08%) repeated. The ion exchange resulted in an FEP dispersion with ⁇ 5 ppm PFOS. No bed blockage was observed.
- Example 9 was repeated with a THV dispersion with a solids content of 20% and an average particle size of 80 nm. Before the anion exchange, the
