Feedstock-Dependent Properties of Degradable Thermosets Derived from Kraft Lignins and Epoxidized Linseed Oil
Brittleness and poor network control limit lignin-based thermosets. Highly bio-based thermosets (∼90% bio-based content) were prepared from oxidized spruce and eucalyptus kraft lignins and epoxidized linseed oil (ELO) via acid−epoxide curing, and poly(ethylene glycol) (PEG) was incorporated to improve toughness, yiel...
