Lignin-containing polyurethane and process for producing the same |
| abstract |
A polyurethane which comprises a polyurethane and a ligninsulfonic acid residue incorporated in the molecular chain of the polyurethane and which is inexpensive and has excellent material properties. The polyurethane is characterized by being obtained by condensation-polymerizing a polyisocyanate with a polyol solution containing ligninsulfonic acid or a partial neutralization salt thereof in a dissolved state, and by having a ligninsulfonic acid content of 1 to 40% based on the whole polyurethane. |
