Description

Sustainable PolymerPolymer products with recycled content are important for a circular economy. Commonly, these products are derived mainly from fossil fuels and contain further a minor recycling content often from an unknown or mixed source. However, these polymer products still exhibit a high product carbon footprint, which is undesirable because it has a negative impact on overall sustainability of the polymer products. In addition, products solely obtained by specific recycling methods, e.g. mechanical recycling, are of poor quality. For this reason, it is an object of the present invention to provide a method for the production of a polymer product, which:leads to product having an enhanced (closed-loop) recycling content,leads to product having a reduced product carbon footprint,leads to product having improved quality, especially mechanical properties,exhibits a reduced energy consumption and / or carbon emission, and / orexhibits improved sustainability;and a polymer (composition / product), which:exhibits an improved (closed loop) recycling content,exhibits a reduced product carbon footprint,exhibits an improved quality, especially mechanical properties, and / orexhibits improved sustainability.The object is at least partially solved by a method comprising the steps, preferably in this order:i) providing a mixture M1 comprising, preferably consisting of:two or more of the following polymers P:polymer PR1,polymer PR2,polymer PR3,polymer PR4,preferably one or more additive(s) AD,preferably polymer PF, andpreferably polymer PB,ii) converting, preferably mixing and heating, the mixture M1 to obtain polymer P1, polymer composition PC1 or product PRF1, andiii) preferably, if in step ii) a polymer P1 or polymer composition PC1 is obtained, converting the polymer P1 or the polymer composition PC1 to obtain a product PRF1.Further, the object is at least partially solved by a polymer P1, polymer composition PC1 or product PRF1, obtainable or obtained by the method described herein.In addition, object is at least partially solved by a use of a mixture M1 comprising, preferably consisting of:two or more of the following polymers P:polymer PR1,polymer PR2,polymer PR3,polymer PR4,preferably one or more additive(s) AD,preferably polymer PF, andpreferably polymer PB,for the production, preferably the sustainable production, more preferably low energy production, of polymer P1, and / or polymer composition PC1 and / or a product PRF1, andpreferably by using the method described herein.Moreover, the object is at least partially solved by a use of a method described herein for the adjustment of a recycling content and / or, preferably and, a product carbon footprint and / or, preferably and, the quality of a polymer P1, polymer composition PC1, and / or a product PRF1.In a preferred embodiment, the polymer PR1 is at least partially, preferably is, obtainable by or obtained by or at least partially derived, preferably derived, from, thermochemical recycling, preferably comprising gasifying, steam cracking and / or pyrolyzing, more preferably gasifying and / or pyrolyzing, a waste W1. Thus, the quality is improved. The process is not particularly limited. A person skilled in the art knows how to conduct the process. An example of the process is described in Zeller, M., Netsch, N., Richter, F., Leibold, H. and Stapf, D. (2021), Chemical Recycling of Mixed Plastic Wastes by Pyrolysis - Pilot Scale Investigations.

Chemical recycling explicitly encompasses depolymerization of polymers, including enzymatic depolymerization.“Depolymerization” refers to a chemical reaction in which a polymer is cleaved into its monomers or oligomers under suitable conditions, such as temperature, pressure, and / or the presence of chemical reagents. Depolymerization also includes enzymatic depolymerization, wherein enzymes act as catalysts to promote the cleavage of polymer chains.“Enzymatic depolymerization” refers to a specific form of depolymerization in which enzymes are employed as catalysts to break down polymers into monomers or oligomers. Enzymatic depolymerization is considered to be both chemical recycling and solvent-based recycling within the meaning of this description.In a preferred embodiment, the polymer PF is at least partially, preferably is, obtainable by or obtained by or at least partially derived, preferably derived, from a fossil source, preferably selected from naphtha and / or coal and / or gas and / or raffinate products.

In examples, in which two components are present, the ratio (wt-% / wt-%) of the components is 2 (fossil): 1 (recycled) and in examples, in which three components are present, the ratio (wt-% / wt-% / wt-%) of the components is 1:1:1. To obtain the polymer compositions, always the same additives were added to the polymer. These additives were excluded for the calculation of the PCF and recycling content. In Table 1, “6” is superior, “5” is very good; “4” is good; “3” is average; “2“ is bad; “1" is unsatisfactory. The values for all examples were obtained by the same method and as described above and compared to each other. For the product quality, mechanical properties (Young's modulus, tensile strength and the elongation at break) can be measured and compared to each other. The values for the availability are based on the current market situation.
