Reprocessable Disulfide‐Based Vitrimers with Adhesive Properties
Macromolecular Rapid Communications, EarlyView.A dual‐curing strategy combining UV‐induced thiol–ene polymerization and thermal thiol–epoxy curing was used to prepare disulfide‐based vitrimer networks with reprocessable, recyclable, and adhesive properties enabled by dynamic disulfide exchange. ABSTRACT A family of disulfide (S–S) containing thiol–vinyl–epoxy dynamic networks are presented.

Robust β‐myrcene block copolymer elastomeric vitrimers
Polymer International, EarlyView.Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Direct transesterification of black soldier fly larvae (Hermetia illucens) for biodiesel production
, 2018 In this study, direct transesterification with a combination of methanol and a cosolvent was demonstrated to be promising for the production of biodiesel from black soldier fly larvae (BSFL) biomass. Of the solvents tested, n-hexane was identified as the

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols
Polymer International, EarlyView.We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.
