摘要: The present invention relates to softwood lignin derivatives having an aliphatic hydroxyl content of from about 2.5 mmol/g to about 7 mmol/g lignin, and the preparation method thereof. The preparation method comprises: pulping a fibrous biomass, heating the biomass, maintaining the elevated temperature for 1 minute or longer, separating the cellulosic pulp to form a lignin-rich material, and recovering derivatives of native lignin. The lignin derivatives have a desired antioxidant activity characterized by radical scavenging index (RSI). Another aspect of the invention relates to compositions comprising the softwood lignin derivative. Another aspect of the invention relates to a use of the softwood lignin derivatives comprising incorporating the softwood lignin derivatives into polymer compositions.

摘要: The present invention provides derivatives of native lignin having a certain aliphatic hydroxyl content. Surprisingly, it has been found that consistent and predictable antioxidant activity may be provided by selecting for derivatives of native lignin having a certain aliphatic hydroxyl content.
