Dicarboxylic acid-epoxy vitrimers: influence of the off-stoichiometric acid content on cure reactions and thermo-mechanical properties

Vitrimers with 1 : 1 to 2 : 1 epoxy/acid ratio and TBD show increased stiffness and gradual transition from an exchangeable to non-exchangeable network.

Influence of treating parameters on thermomechanical properties of recycled epoxy-acid vitrimers

The effects of particle size, temperature, time, and pressure on the mechanical properties of regenerated epoxy-acid vitrimers were investigated, which helped to refine the vitrimer reprocessing condition parameter toolbox.

Total synthesis and structure revision of chrysamide B

Total synthesis and structure revision of chrysamide B are described, the strategy features a convergent assembly of the chiral piperazine core and epoxy-acid.

Shape memory epoxy vitrimers based on DGEBA crosslinked with dicarboxylic acids and their blends with citric acid

The shape of epoxy–acid based vitrimers can be changed either temporarily or permanently by selecting the appropriate thermal treatment.

Diterpenes from Sideritis infernalis and S. candicans

A phytochemical study of Sideritis infernalis led to the isolation of the new nor-diterpene adejone (17-nor-7α,18-dihydroxy-ent-kaur-16-one). The biosynthesis of this compound implies the decarboxylation of an epoxy-acid as the last step. In addition, three diterpenes with an ent-kaurene skeleton, episideridiol, candicandiol 7α-monoacetate and candidiol 15α-monoacetate, have been isolated from S. candicans for the first time in nature.
