Lignin copolymer Molecular weight

It is recommended that a reslurry of crude OSL in an organic solvent or 10% aqueous salt (e.g., NaHCOa) solution be performed to remove low-molecular-weight (mono-functional) species, waxes, and carbohydrates. This purification leads to an improvement in OSL reactivity and contributes to the usefulness of OSL as a PF resin extender or PF copolymer raw material. It is presumed that extraneous removed materials in the crude lignin react with formaldehyde but do not lead to productive cross-linking polymer formation. [Pg.333]
