Tannin and lignin were blended with polypropylene (PP) through dynamic vulcanization technique. Their influence of mechanical property, crystallinity, thermal stability, as well ultraviolet (UV) protection property on the PP matrix was investigated compared native tannin lignin. According to our experimental results, undergo more compatible matrix. Besides, vulcanized can perform nucleating agents because their relatively small particle size. Moreover, tannin/lignin have a better performance stability tannin/lignin, especially PP/vulcanized blend. Furthermore, present UV protective performance, concluded from fewer changes surface morphology, carbonyl index, viscosity, tensile property.
