Aromatic alcohol-lignin-aldehyde resins and process for making and using same. In some examples, a process for making a resin can include heating a first mixture that includes a lignin, an aromatic alcohol, and a base compound to produce a second mixture that can include an activated lignin, the aromatic alcohol, and the base compound. The second mixture can be heated with an aldehyde to produce a third mixture that can include an aromatic alcohol-lignin-aldehyde resin and unreacted free aldehyde. In some examples, an aromatic alcohol-lignin-aldehyde resin can be or include a co-polymer of an activated lignin, an aromatic alcohol, and an aldehyde. A weight ratio of the activated lignin to the aromatic alcohol can be about 20:80 to about 95:5.

A modified lignin having a ratio ((2H+G)/S) of a total of twice of a relative existence ratio H (%) of an H-type skeleton and a relative existence ratio G (%) of a G-type skeleton with respect to a relative existence ratio S (%) of an S-type skeleton, obtained from integrated values measured by .sup.31P-NMR, of 2.5 or more, and an existence ratio of an aliphatic hydroxy group obtained by the same method of less than 20%, a method for producing a modified polyphenol, and a modified lignin-containing resin composition material.

A lignin dispersion composition comprising spherical lignin particles dispersed in an aqueous medium, wherein the spherical lignin particles have a size exclusively within a range of 100 nm to 5 microns. Also described herein is a method of producing the lignin dispersion, by: (i) dissolving lignin in an organic solvent substantially devoid of water yet miscible with water to result in a solution of the lignin in the organic solvent; and (ii) producing the lignin dispersion by dialyzing the solution of the lignin with water until substantially all of the organic solvent is replaced with water with simultaneous formation of spherical lignin particles dispersed in the water. Also described herein is a method for stabilizing an emulsion by intimately mixing the emulsion with the lignin dispersion. Also described herein is a hierarchical assembly of porous microparticles produced by mixing the lignin dispersion with an emulsion and an amphiphilic block copolymer.
