Abstract: Disclosed is a method comprising: a) dispersing lignin into an alcohol-containing compound having a boiling point in the range of 120°C to 300°C to form a lignin dispersion; and b) contacting the lignin dispersion with an alkylene carbonate, optionally in the presence of a basic compound, at a temperature in the range of from 120°C to 200°C and a period of time in the range of from 0.25 hours to 24 hours to form an alkoxylated lignin dispersion.
