Resin compositions comprising lignin derivatives

摘要

The present invention provides derivatives of native lignin having an ethoxy content of 0.45 mmol/g or greater. Surprisingly, it has been found that phenolic resins comprising derivatives of native lignin having ethoxy contents have acceptable performance characteristics such as bondstrength.

主权项

1. A lignin derivative extracted from a lignocellulosic biomass, wherein immediately following extraction the lignin derivative has an ethoxy content of from 0.5 mmol/g to 1.4 mmol/g, a polydispersity of from about 1.2 to about 4, and an aliphatic hydroxyl content of from about 0.2 mmol/g to about 6.5 mmol/g.
