摘要： Disclosed herein are systems and methods of depolymerizing a lignin component of a lignin-containing material. The method comprising contacting the lignin-containing material with a solvent and optionally a catalyst at a temperature in the range of 180-300° C. and at a maximum operating pressure of less than 10 barG during the depolymerization of the lignin component of the material and collecting at least one volatile stream comprising one or more depolymerized lignin products. In an embodiment, the step of contacting is carried out in a reactive distillation reactor, and the step of collecting comprises concurrently collecting at least one volatile stream via distillation apparatus connected to the reactive distillation reactor, at least one of the one or more depolymerized lignin products comprises a substituted phenol having the following general formula: (I) wherein R1 is H, methyl, ethyl, n-propyl, propenyl, or allyl, and R2 and R3 are independently selected from H or methoxy group.

摘要： 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.

摘要： The present invention pertains to bio-based block polymers synthesized from functionalized lignin-based molecules (A-monomer) and functionalized fatty acids or fatty alcohols (B-monomer) derived from plant or animal oils, waxes or fats. The block polymers can be synthesized via numerous polymerization techniques, such as reversible addition-fragmentation chain transfer (RAFT). Most importantly, this class of bio-based block polymers shows promise as providing sustainable yet scalable and tunable thermoplastic elastomers and pressure-sensitive adhesives, among other applications.

摘要： A coating head includes a coating device and at least a first flexible blade that is capable of being shaped into contact with a solvent-containing film on a substrate upon pressing the first flexible blade against the film, thereby providing contact between the blade and the film over a contact distance when the coating head is drawn over the substrate. The coating device and the blade are separated by a spacing distance such that partial loss of solvent occurs from a starting film formed on the substrate by the coating device as the coating head is drawn over the substrate, the partial solvent loss forming the solvent-containing film. A method of producing a film having a hierarchical structure includes drawing a coating head across a substrate to form on the substrate via the coating device a starting film including a solvent and a material for forming the hierarchical structure.

摘要： Dimethoxyphenol-based monomers containing polymerizable functional groups such as [meth]acrylate groups are useful for the preparation of polymers, wherein one or more dimethoxyphenyl moieties are part of side chains pendant to the backbones of the polymers. The polymers thereby obtained may have different, improved properties, such as higher glass transition temperatures, thermal stability and solvent resistance, as compared to polymers based on other types of lignin-derived monomers.
