Description

Process for recycling a composition comprising a poly(urea-urethane) polymer with hindered urea bondsThe present invention relates to a process for recycling a composition comprising a poly(urea-urethane) polymer with hindered urea bonds comprising the treatment of the composition comprising the poly(urea-urethane) polymer under conditions suitable to at least partially cleave the urea bonds of the polymer.There is a need in the material and polymer sciences to develop polymeric materials with desired in-use performance characteristics that are also malleable, repairable, and shape reprogrammable. There is also a need to develop such polymers that can be degraded or reversibly depolymerized. Even though shape memory and self-healing polymers are known, many of these polymers do not have both the desired performance and dynamic characteristics. With respect to degradable or reversibly depolymerizable polymers, these polymers often lack the required in-use performance characteristics and are either too easily degraded or on the other hand not degraded as readily or rapidly as desired.Further, composite materials based on polymers comprising fillers such as fibrous materials or isotropic materials, for example glass fibers reinforced plastics (GFRP), are widely used in applications such as airplanes, boats or windmill blades. Over 10 million of tones of GFRP are produced every year and no feasible recycling concept exits once embedded into the polymers.Due to their excellent dimensional stability, chemical resistance, and thermal and mechanical performances, thermosets are used in a wide range of applications, including structural composites, adhesives, coatings, and electrical insulation. However, conventional thermosets cannot be reshaped, reprocessed, or recycled due to their inability to melt or flow at high temperatures.An effective chemical strategy to combine these properties is to introduce dynamic chemical bonds into a polymer network, resulting in a dynamic polymer network. Polymers containing dynamic bonds are considered covalent adaptable networks (CANs).Several scientific publications disclose that urea bonds bearing a bulky group on the nitrogen atom resulted in hindered urea bonds (HUBs) that were dynamic and can reversibly dissociate into an amine and isocyanate based on the associative exchange mechanisms. However, those documents do not disclose processes suitable for industrial processes on a large scale which allow to recycle waste materials on a large scale.Thus, there is a need to develop processing techniques to recover materials from plastic waste. The recycling process should reduce both the waste of material and the carbon footprint. Further, it should be an economical and energy efficient process delivering valuable materials which comprise high technical features. In contrast, disposal, e.g. by combustion, has a negative impact on the environment as well as on the carbon footprint. Therefore, it was an object of the present invention to provide an improved process for recycling of poly(urea-urethane) polymer.Surprisingly, it was found that the recycling process according to the present invention permits to reduce both the waste of materials and the carbon footprint. Further, the recycling process according to the present invention permits an economical and energy efficient process contrary to the disposal, e.g. by combustion, which has a negative impact on the environment as well as on the carbon footprint.Therefore, the present invention relates to a process for recycling a composition comprising a poly(urea-urethane) polymer (PUU1) comprising:(a) treatment of the composition comprising the poly(urea-urethane) polymer (PUU1) under conditions suitable to at least partially cleave the urea bonds of the polymer, obtaining a mixture (M1) comprising one or more prepolymers, the poly(urea-urethane) polymer (PUU1) being obtainable or obtained by a process comprising:I) providing one or more isocyanates;

Preferably, the process of the present invention allows the complete recovery of the poly(urea-urethane) and expensive fillersused, such as carbon fibers from the composites. Surprisingly, it was found that the polymer according to the present invention permits to create composites which can be used in many applications while being easily repairable and recyclable. Indeed, the poly(urea-urethane) polymer according to the present invention has dynamic hindered urea bonds (HUBs) which acts as dynamic covalent bonds in a covalent adaptable system / network (CAS / CAN). It is thus believed that the introduction of bulky substituent to a nitrogen atom weakens the bond such that there is a dissociation equilibrium of open and closed bonds which shifts to the open side by increasing temperature. The HUBs split up to the original constituting groups (de-polymerisation). The embodimented materials are easily processable by thermo-mechanical processing methods as demonstrated in the following and facilitate the chemical and mechanical recycling of the poly(ureaurethane) polymers.According to the present invention, the treatment according to step (I) may be applied to a formed body or also parts of a formed body. The composition might for example be cut into small pieces before the treatment or also comminuted using standard procedures.In the context of the present invention, a "thermoset polymer” refers to a network polymer, comprising covalently bonded structures having at least three points of covalent bond attachment between polymer chains, wherein preferably the at least three points of covalent bond attachment between polymer chains forms part of a polymer network.In the context of the present invention, a "thermoplastic polymer” refers to a material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling, consisting of linear polymer chains with little or no branching, comprising covalently bonded structures having two points of covalent bond attachment between polymer chains, wherein preferably the two points of covalent bond attachment between polymer chains forms part of a linear polymer system.In the context of the present invention, an isocyanate is a general term for a molecule that comprises at least one isocyanate functional group.

When the MDI was melted, the corresponding amine was added. The mixture was stirred for 30 min. Table 1 shows the composition and properties of the tested prepolymers.Reference Example 10: Determination of the NCO valueNCO values were determined by titration with a Metrohm Modell 916 Tl-Touch. 0.1-0.3 g of the prepolymer was dissolved in 40 mL THF and 10 mL of dibutylamine solution (2% in xylene) was added. The potentiometric titration was performed with 0.1 M HCI.Reference Example 11 : Determination of the viscosity of the mixture comprising the prepolymerViscosity of the mixture comprising the prepolymer was determined by rotational rheometry at 23°C, 100 1 / s and 5 min with a CP 50.Reference Example 12: Determination of the curing behaviourThe curing behaviour was determined according to DIN 16945. Rotational rheometry was performed at different temperature (23, 60, 80 and 100°C) at 100 1 / s with a CP 50 after 10 min after mixing. The curing time was determined at 15000 mPas.Example 13: Preparation of a poly(urea-urethane) polymer according to the present inventionPolyols 1 and 2 were dried under vacuum. 130 g of the prepolymer obtained according to reference Example 1 and 65 g of the polyol mixture (molar ratio 1 :1 n:n) were combined and speed mixed for 20-120 s at 2000 rpm. The mixture was degassed and poured into a mold. The mixture was precured at 105°C for 60 min and then cured again at 150°C for another 60 min.Table 2 shows the different obtained poly(urea-urethane) polymer mixtures and their properties.Comparative Example 14: Preparation of a polymer not according to the present invention50 g of 2,4-diphenylmethane diisocyanate (MDI) was immersed in a flask and heated to 30°C. When the MDI was melted, 5,0 g of BDO was added. No reaction occurred. The mix was slowly heated to 40°C. An exothermic reaction takes place and the mix turned solid.It is not possible to synthesize a prepolymer with BDO. All ingredients were thus mixed directly to obtain a comparative material:22.2 g of 2,4-diphenylmethane diisocyanate (MDI), 10.0 g Polyol 1, 4.75 g Polyol 2 and 2.90 g 1 ,4-butandiol were speed mixed at 2000 U / min for 1 min. The mixture was poured into a mold and cured at 150 °C for 1 h.Table 3 shows the properties of the polymer obtained according to Comparative Example 14.Comparative Example 15: Preparation of a polymer not according to the present inventionIt is not possible to synthesize a prepolymer with BDO. All ingredients were thus mixed directly to obtain a comparative material:5.0 g of 2,4-diphenylmethane diisocyanate (MDI), 2.6 g Polyol 1, 1.2 g Polyol 2 and 0.5 g 1,4-butandiol were speed mixed at 2000 U / min for 1 min. The mixture was poured into a mold and cured at 150 °C for 1 h.Table 4 shows the properties of the polymer obtained according to Comparative Example 15.Comparative Example 16: Preparation of a polymer not according to the present invention6.15 g of 2,4-diphenylmethane diisocyanate (MDI), 3.19 g Polyol 1, 1.51 g Polyol 2 and 1.85 g DIB-MDA were speed mixed at 2000 U / min for 1 min. The mixture was poured into a mold and cured at 150 °C for 1 h.Example 17: Testing the pot life of Example 2d and Comparative Example 16The pot life of the samples was measured according to Reference Example 6.Table 5 shows the viscosities of the mixtures obtained according to Comparative Example 16 and Example 2d.As can be seen from the results in Table 5, the initial viscosity of Example 2d according to the invention is lower than the initial viscosity of comparative Example 16. Further, the pot life of Example 2d is longer than the pot life of Comparative Example 16. Therefore, the preparation of a prepolymer consisting of isocyanate and SHA has a positive effect on the curing behavior.Example 18: Preparation of a composite according to the present invention comprising glass fibers53.75 g of 2,4-diphenylmethane diisocyanate (MDI) were weighed into a 500 mL 4-neck flask and heated in an oil bath to 40°C. At about 40°C, 46.15 g DIB-MDA were added rapidly. The mixture was stirred for 30 min in an oil bath at 40°C and then the mixture was degassed for 10 min at about 20 mbar until the mixture no longer foamed. Then 118 g of a polyol 1 and polyol 2 mixture (80 g of polyol 1 and 38 g of polyol 2) were added at 50°C. The mixture was degassed for 5 min at 45°C and 20 mbar.A mold was heated to 50°C and sprayed with Indrosil 2000. A thin layer of liquid product was poured into the bottom of the mold and then a fiberglass plate was laid on top. More of the liquid product was poured over the fiberglass plate. The mold was closed with a lid and the mold was heated to 105°C. The plate was precured for 1 h at 105°C and then removed from the mold. Then it was cured for another hour at 150°C.Example 19: Mechanical RecyclingThe tested material was cut (0.2 x 0.2 x 0.2 cm3) and transferred to a hot press. The samples were pressed at 20 kPa for 5 min at different temperatures.Table 6 shows the malleability of the tested materials at different temperatures.A thin foil was obtained for the samples of Examples of 2b, 2d, 4, 5 and 9 showing that the materials are mechanically recyclable in contrast to the samples of Comparative Examples 14 and 15.Example 20: Chemical RecyclingThe tested material was heated in y-Valerolactone (3g y-Valerolactone per 1 g of tested material) for 24 h at 130°C under stirring. The tested sample was soluble if a homogeneous solution was obtained.To obtain the soluble prepolymer, 1 g of the tested material was immersed in 3 g of 1,4-dioxane. An excess of D I B- MDA was added (2 eq per urea bond), and the mix was stirred under reflux for 24h. A soluble amine-terminated prepolymer was obtained when the dioxane was removed under reduced pressure at 60°C and a stable liquid is obtained.Table 7 shows the solubility of the tested materials in y -Valerolactone.21. IR measurementsTo show the enhanced reversibility of the secondary hindered urea bonds measurements with a temperature dependent IR spectrometer have been conducted.IR spectra were recorded on a Bruker Tensor II system equipped with a specifically designed heat stage addon for high throughput temperature-depended IR measurements in the sample compartment. Samples were prepared atthin foils and put on a Si-wafer. Temperature was increased in 20°C steps and the sample was kept at this temperature for 10 min. The intensity of the NCO band at was monitored at the integral of the band at 2280 cm-1 as a function of time (and temperature).Mixture: 20 mmol MDI, 8 mmol of BDO (reference) (or DIB-MDA, DIB-Butandiamine, DIB-Methylcyclohexandiamine, DIP-Methylcyclohexandiamine, DIB-Hexandiamine, Dibenzylethylendiamin, Dibenzyl-MCDA, 2-Ethylhexyl MCDA, Baxxodur PC136, 2-(Ethylamino)ethanol, N-(2-Hydroxyethyl)anilin) and 12 mmol of polyTHFI 000 were mixed, applied to a Si-wafer and cured at 150°C for 2 h.Reversibility of the formed bond was shown by the appearance of the NCO band at 2280 cm-1 in the IR spectrum at elevated temperatures.The intensity of the NCO band was monitored with time / temperature:Table: intensity of the NCO bandThe measurements show that following amines / hydroxyamines show enhanced reversibility compared to the reference sample BDO:DIB-MDADIB-ButandiamineDIB-MethylcyclohexandiamineDIP-MethylcyclohexandiamineDIB-HexandiamineDibenzylethylendiaminDibenzyl-MCDA2-Ethylhexyl MCDAN-(2-Hydroxyethyl)anilinThe following amines show similar, i.e. hardly / no reversibility, like BDO:2-(Ethylamino)ethanolBaxxodur PC13622. Variation of the isocyanateDIB-MDA has been combined with multiple isocyanates: TDI100: Pure 2,4-toluene diisocyanate, TDI80: 80 % 2,4- isomers and 20 % 2,6-isomers of toluene, HDI: hexamethylene diisocyanate , pMDI: polymethylene polyphenyl isocyanate (Lupraphen M20 S) and Basonat HA 3000, an aliphatic HDI-derivative with a functionality of 2.44.Mixture: 5 g of respective isocyanate, 40% NCO groups reacted with DIB-MDA, 60 % of NCO groups reacted with polyTHFIOOO.Reversibility of the formed bond was shown by the appearance of the NCO band at 2280 cm-1 in the IR spectrum at elevated temperatures.Table:All tested isocyanates showed reversibility. This indicates that aliphatic and aromatic isocyanates with a functionality of >= 2 are suitable for this invention.Another characteristic of utility of the invention is the viscosity of the prepolymers. A prepolymer with <100000 mPas is still liquid enough and could be used to achieve a processable formulation. DIB-MDA has been mixed in different amounts with different isocyanates. As can be seen, the viscosity of the prepolymer increases exponentially with the content of the secondary amine. The steepest increase was obtained with pMDI. The lowest increase was obtained with aliphatic isocyanates (HDI, Basonat 3000). TableFor a mixture of MDI and DIB-MDA the ideal amine content at room temperature was determined to be 30 wt.%.Above that value the polymer became too viscous and could not be mixed with the polyol components. Starting from >43% no homogeneous prepolymer could be obtained anymore.Table:23. Curing Behavior Prepolymer vs. Single ComponentsTo determine if pre-reacting the amine with the isocyanate benefits viscosity and pot life, a curing study following DIN 16945 was conducted. The mixtures' properties of the prepolymer with the polyol (PP) were compared to those without prior prepolymer synthesis (SC). The isocyanate MDI was mixed directly with the amine DIB-MDA and the poly- ols (Lupranol 1200 and Lupranol 3506 / 1 in a 1 : 1 n : n mix) as single components (SC). The viscosity with time and the pot life (time to reach 15000 mPas) have been compared at different temperatures. At room temperature the differences were significant. The samples, where the prepolymer was used had a much lower initial viscosity and ahigher pot life. The effect was less pronounced at 60°C, but still well visible. Above the Tg of the system, the prepolymer mixes and the single component mixes displayed the same behavior. This experiment showed that the use of prepolymer has advantage on viscosity and curing time at lower temperatures.24. Recycling propertiesThe tested material was cut (0.2 x 0.2 x 0.2 cm3) and transferred to a hot press. The samples were pressed at 20 kPa for 5 min at different temperatures. The material 2d (Vitrimer) was malleable starting from 130°C. The comparative example 15, where DIB-MDA was replaced by an equimolar amount of BDO (Standard) crumbled under pressure and heat.For chemical recycling via solvolysis several solvents have been attempted. The samples were immersed to form a 10 wt% solution and the solvent was heated to reflux or max. 130°C. When the sample did not dissolve after 24 h in the pure solvent, an excess of DIB-MDA was added to scavenge the open NCO bonds to facilitate the dissolution. The vitrimer resin was soluble in DMI and GVL. It was also soluble in 1 ,4-dioxane, but only with the addition of additional amine. The reference sample was not soluble in these solvents within 24 h. The vitrimer resin was not soluble in toluene, xylene and MEK.Cited LiteraturePrior Art Disclosure; Issue 684; paragraphs
