Preparation of environmental friendly phenol-formaldehyde wood adhesive modified with kenaf lignin

- Isolation of Kraft and organosolv lignin from Kenaf core.
- Higher molecular weight of Kraft lignin was probably due to the more severe reaction condition.
- Preparation of lignin phenol formaldehyde (LPF) wood adhesive.
- 50% KLPF adhesive shows higher tensile strength than that of commercial PF.
