Abstract

PEGylated or oxyethylated lignins (OEL) have recently become a hot topic as precursors for novel lignin-based and sustainable materials or active substances such as hydrogels, aerogels, carbogels, dispersants, and surfactants. Since functional properties of OEL and the resulting materials are strong...
