The fast biodegradation rate and inflammability of polybutylene succinate (PBS) severely restrict its applications in many areas. To solve the above problems and broaden its applications, herein, a halogen-free flame retardant (CP-lignin) based on lignin was successfully synthesized. After adding 30wt% CP-lignin into PBS, the peak heat release rate and total heat release of PBS are remarkably reduced by 27 and 31%, respectively. Additionally, the higher char yield was beneficial to improving the flame retardant properties of PBS. After adding 10wt% CP-lignin, the ratio of weight loss is reduced by about 33%, and the ratio of weight loss is decreased gradually as the CP-lignin loading increases. This research provides a reasonably way to make full use of the lignin and to broaden the application of PBS. At the same time, it also provides a new idea for the production and preparation of completely biodegradable materials.
