| 摘要 |
A flame retardant resin composition, containing a thermoplastic resin and a flame retardant, wherein the flame retardant contains a nitrogen-containing structure-introduced phosphorylated lignin derivative, wherein the nitrogen-containing structure-introduced phosphorylated lignin derivative is produced by introducing a nitrogen-containing structure into a lignin derivative and adding a phosphoric acid to the lignin derivative, or by adding a phosphoric acid to a lignin derivative and introducing a nitrogen-containing structure into the lignin derivative, or by introducing a nitrogen-containing structure into and adding a phosphoric acid to a lignin derivative simultaneously, and wherein the lignin derivative is obtained by subjecting a naturally occurring lignin to a treatment for allowing the naturally occurring lignin to be decomposed into small molecules or to be water-soluble. |
