## Abstract The networkโ€forming behavior, gelation, and vitrification of ligninโ€polyetherโ€copolymerโ€epoxide/amine resins were determined using a recently described dynamic mechanical thermal analysis (DMTA)โ€based method. Six resins were studied which differed in lignin content, polyether arm length
