Abstract
A flame retardant resin composition including: a thermoplastic resin; and a flame retardant, wherein the flame retardant includes a phosphorylated lignin derivative, and wherein the phosphorylated lignin derivative is produced by adding phosphoric acid to a lignin derivative obtained by subjecting a naturally occurring lignin to a predetermined treatment.
Claims7
A flame retardant resin composition comprising:
- a thermoplastic resin;
- and
- a flame retardant,
- wherein the flame retardant comprises a phosphorylated lignin derivative, and
- wherein the phosphorylated lignin derivative is produced by 1) hydroxymethylating a lignin derivative obtained by subjecting a naturally occurring lignin to a predetermined treatment, and then 2) adding phosphoric acid to the hydroxymethylated lignin derivative.
