TL;DR: In this article, the state of the art in the field of chemical recycling of poly(ethylene terephthalate) (PET) is reviewed and the theoretical basis of the ester bond cleavage and a wide spectrum of degrading agents and final products are presented.
Abstract: This paper reviews the state of the art in the field of chemical recycling of poly(ethylene terephthalate) (PET). Advantages of the chemical recycling of PET, the theoretical basis of the ester bond cleavage, and a wide spectrum of degrading agents and final products are presented. Chemical processes applied in polymer recycling are divided into six groups: methanolysis, glycolysis, hydrolysis, ammonolysis, aminolysis, and other methods. Numerous possibilities for the utilization of waste PET as a very useful raw chemical material are described on the basis of literature. A comparison of chemical recycling methods is carried out. The following aspects were taken into consideration: (i) flexibility in utilizing a variety of waste types, (ii) conditions necessary for degradation including safety requirements, (iii) economic aspects, and (iv) product versatility. A total of 108 references including 46 patents are cited in this paper.

TL;DR: The bottlebrush melts and elastomers exhibit an unprecedented combination of low modulus, high strain at break (∼1,000%), and extraordinary elasticity, properties that are on par with those of designer gels.
Abstract: Solvent-free, supersoft and superelastic polymer melts and networks made from bottlebrush macromolecules can display low modulus, high strain at break, and extraordinary elasticity. Polymer gels are the only viable class of synthetic materials with a Young’s modulus below 100 kPa conforming to biological applications1,2,3, yet those gel properties require a solvent fraction4,5,6,7. The presence of a solvent can lead to phase separation, evaporation and leakage on deformation, diminishing gel elasticity and eliciting inflammatory responses in any surrounding tissues. Here, we report solvent-free, supersoft and superelastic polymer melts and networks prepared from bottlebrush macromolecules. The brush-like architecture expands the diameter of the polymer chains, diluting their entanglements without markedly increasing stiffness. This adjustable interplay between chain diameter and stiffness makes it possible to tailor the network’s elastic modulus and extensibility without the complications associated with a swollen gel. The bottlebrush melts and elastomers exhibit an unprecedented combination of low modulus (∼100 Pa), high strain at break (∼1,000%), and extraordinary elasticity, properties that are on par with those of designer gels8,9.

TL;DR: There is a persistent interest in extending cosmology beyond the standard model, ΛCDM, motivated by a range of apparently serious theoretical issues, involving such questions as the cosmological constant problem, the particle nature of dark matter, the validity of general relativity on large scales, the existence of anomalies in the CMB and on small scales, and the predictivity and testability of the inflationary paradigm as mentioned in this paper.
