Discovered by Wurtz in 1848, the isocyanates revealed their chemistry from systematic study
during the nineteenth century, for example, by Curtius or Hofmann. The discovery of …

Polyurethanes (PUs) represent a family of useful synthetic polymers (thermoplastic or
thermosetting) obtained from diisocyanates and diols/polyols via polycondensation …

While transesterification has been largely explored by chemists, only a few studies
comparatively dealt with its “sluggish cousin”, transcarbamoylation. Originally suggested 70 …

The recycling of any kind of plastic to convert it in valuable products is one of the main
challenges of today's society. Besides, if the recycling process is itself green, then it would …

Acidolysis is emerging as a promising method for recycling polyurethane foam (PUF) waste.
Here, we present highly efficient acidolysis of PUFs with adipic acid (AA) by heating the …

The increased applications of Polyurethane (PU) materials give rise to a higher amount of
wastes, which have a devastating effect on the earth in turn; therefore, the management of …

Conspectus The mismanagement and leakage of plastic waste into the environment are
failures of modern society. Once in the environment, plastic waste degrades into …

The design of circular polymers has emerged as a necessity due to the lack of efficient
recycling methods for many commodity plastics, particularly those used in durable products …

The use of polyurethanes and, therefore, the quantity of its scrap are increasing.
Considering the thermoset characteristic of most polyurethanes, the most circular recycling …

Polyurethane (PU) is a highly engineered and cross-linked polymer found in a plethora of
materials such as mattresses, shoes, windmills, and insulation of refrigerating appliances …
