Lignin copolymer Solubility

Alkaline methanolysis of graft vinyl acetate-lignin copolymers (Samples LVAO, LVAl, and LVA60) led to the corresponding water-soluble vinyl alcohol copolymers, whose lignin content, as determined by the absorption at 280 nm, resulted to be substantially higher than in the parent VAc copolymer samples hydrolyzed samples, respectively, thus demonstrating however the formation of copolymer macromolecules. [Pg.147]

It is possible to use lignin directly, without any chemical modification, to obtain rigid PU foams that can be used as a filler or dissolved in polyether polyols. Thus, lignin was dissolved in polyether polyol PO-EO copolymer (in PO homopolymers it is not soluble). The resulting solution of lignin in polyether polyols was used to obtain various PU [23]. [Pg.443]
