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.

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 ...

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 ...

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 ...

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 ...

The textile fibers or the fabric may cause the skin irritation, or more commonly, a contact allergy to the chemical additives ... available for polyester allergic reactions. Until proper diagnosis ...

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 ...

Through further chemical reactions, for instance ... Kinetically Enhanced Access to a Dynamic Polyester Platform via Sequence Selective Terpolymerisation of Elemental Sulfur, Angewandte Chemie ...
