In 2011, a new type of polymer materials was introduced: vitrimers are chemically very stable materials that can be used for structural applications.
Besides, due to their unique chemical properties, they can easily be reprocessed, repaired and recycled as is the case for classic materials such as glass and metal.
Although research on vitrimers is still in an early stage, a lot of interest from industry was already expressed. With renewed fundamental insights on the chemical process of the reprocessing, the researchers succeeded in controlling the properties and reprocessing of vitrimers by addition of specific additives, both for rubbers and hard plastics (Nature Communications, "Chemical control of the viscoelastic properties of vinylogous urethane vitrimers").
As one type of starting material is now employable in very different and demanding applications, this research is a big leap forward towards the use of recyclable plastics.
