Disclosed herein is a bio-based copolymer comprising in polymerized form (i) at least one polymerizable bio-based monomer containing one phenolic hydroxyl group which has been derivatized to provide at least one polymerizable functional group which is an ethylenically unsaturated functional group (such as a [meth]acrylate group), where the precursors of the polymerizable bio-based monomers are derived from raw lignin-containing biomass, and (ii) at least one ion-conducting co-monomer other than the bio-based monomer. Also disclosed herein are binders comprising the bio-based copolymer, electrodes comprising the binder, polymer electrolytes comprising the bio-based copolymer and an electrochemical device comprising an electrode in electrical contact with a polymer electrolyte, wherein at least one of the electrode and the polymer electrolyte comprises the bio-based copolymer.

Ion-conducting bio-based polymers from raw lignocellulosic biomass

Disclosed herein is a method of making polymerizable bio-based monomers containing one phenolic hydroxyl group which has been derivatized to provide at least one polymerizable functional group which is an ethylenically unsaturated functional group (such as a [meth]acrylate group), where the precursors of the polymerizable bio-based monomers are derived from raw lignin-containing biomass. Also disclosed herein are bio-based copolymers prepared from such bio-based monomers and a co-monomer, and methods of making and using such bio-based copolymers. In particular, the bio-based copolymers can be used as pressure sensitive adhesives, binders, and polymer electrolytes.

Bio-based polymers from raw lignocellulosic biomass

The present disclosure is directed to stress-responsive compositions comprising (1) at least one (co)polymer comprising at least one mechanophore comprising at least one thiocarbonylthio functional group or derivative thereof and (2) at least one compound comprising at least one functional group capable of reacting with a free radical, The present disclosure is also directed to articles, coatings, and 3D printing binders comprising such stress-responsive compositions, as well as to processes of imparting the abilities of forming and maintaining protective barriers and mechanical self-healing to such articles, coatings, and 3D printing binders by incorporating such stress-responsive compositions therein.

Stress-responsive compositions and uses thereof

Biorenewable additives or modifiers can be used for improving the performance of biorenewable thermoplastics. Modified natural oils, unmodified natural oils, and compatibilizers, as well as mixtures thereof, can be used in combination with a biorenewable thermoplastic such as polylactide (PLA) in order to produce an improved thermoplastic. Modified natural oils include acrylated epoxidized soybean oil (AESO), unmodified natural oils include unmodified soybean oil (SYBO), and the compatibilizers may be star polymer compatibilizers. The improved thermoplastic may have improved tensile properties with little plasticization.
