Indeed, the base rubber is crucial to take advantage of its good elastomeric mechanical properties, and the vitrimer chemistry is the only dynamic chemistry that combines recyclability with full solvent resistance. Provide natural rubber with vitrimer properties is still a very interesting challenge to tackle.

In the case of rubber waste, energy recovery and recycling are the two more widely used methods while prevention still needs to be developed. Recent progresses in organic and polymer chemistry offer new possibilities that may help to improve the end-of-life management of rubbers.

Abstract Cross-linked rubbers used in everyday life, thermoset by nature, represent a major environmental problem at their end of life. The European Union has introduced a hierarchy in waste management from the least to the most favourable solution: landfill disposal, energy recovery, recycling, re-use and prevention. In the case of rubber waste, energy recovery and recycling are the two more ...

Catalytic Control of the Vitrimer Glass Transition | ACS

Vitrimers, strong organic glass formers, are covalent networks that are able to change their topology through thermoactivated bond exchange reactions. At high temperatures, vitrimers can flow and behave like viscoelastic liquids. At low temperatures, exchange reactions are very long and vitrimers behave like classical thermosets. The transition from the liquid to the solid is reversible and is ...

Devulcanization of Natural Rubber in Composites

ABSTRACT. In this study, the effects of the devulcanization process realized by an intermeshing co-rotating twin-screw extruder (ICTSE) on three vulcanized Natural Rubber (NR) composites with different crosslink densities (CD) have been investigated.

Metal-Catalyzed Transesterification for Healing

Catalytic control of bond exchange reactions enables healing of cross-linked polymer materials under a wide range of conditions. The healing capability at high temperatures is demonstrated for epoxy–acid and epoxy–anhydride thermoset networks in the presence of transesterification catalysts. At lower temperatures, the exchange reactions are very sluggish, and the materials have properties ...

Vitrimers are a class of plastics, which are derived from thermosetting polymers (thermosets) and are very similar to them. Vitrimers consist of molecular, covalent networks, which can change their topology by thermally activated bond-exchange reactions.
