AbstractLignin is a polyol and also polyphenol in plant stem and the second most abundant natural polymer coming only next to cellulose. It is an attractive biomass since it is readily available and relatively inexpensive. Currently lignin is mostly used to be burned for energy or to recover for chemicals. Significant research interest has been focused on utilizing lignin as a polymer or filler since last century [1, 2]. However the properties of the lignin based composites by adding lignin as particulate filler to a second polymer are far from satisfactory, due to the complex and heterogeneous structure and chemistry of lignin which are highly dependent on the lignin sources and processing conditions. In this study, the PP lignin composites were extruded in a twin screw extruder. The effects of lignin concentration and lignin type (kraft-wood and soda-rice) on the morphology and performance of PP lignin composites were systematically investigated, and the effect of coupling agent types was also evaluated.
