The product polyesters had M n values of 560–3690 and the double-bond content values were 1.2–3.1 per molecule. The product is a reactive polyester, as demonstrated by a crosslinking reaction.

For pure polyester fabric, the reaction converted 90% of the polyester into a molecule called BHET, which can be directly recycled to create more polyester textiles. The researchers found that the ...

These catalysts are effective in breaking down polyester based on the same chemical reaction (transesterification) and have been shown to be capable of converting polyester into raw materials with ...

It is a non-reversible chemical reaction. The “side-by-side” nature of this cross-linking of the molecular chains tends to means that polyester laminates suffer from brittleness when shock loadings ...

For the production of polyester as described in their study, the chemists used carbonylation to obtain the ester groups. "The problem is that Undecenol reacts with another smaller molecule ...

Researchers found they could separate blended cotton and polyester fabric using enzymes -- nature's tools for speeding chemical reactions. Ultimately, they hope their findings will lead to a more ...

Here’s why. To make new polyester, you need to start with coal, petroleum, air, and water. These materials have to go through a chemical reaction called polymerization, at extremely high heat. This ...

One leading theory on the origins of life on Earth proposes that simple chemical ... polyester microdroplets could form even in salt-rich environments, at low αHA concentrations, and in small ...
