Recently lignin has been attracting a growing interest as a novel eco-friendly material due to its abundant availability and it’s potential as low cost filler. Biobased blends from polypropylene (PP) and lignin were fabricated by extrusion followed by injection moulding. In order to improve the compatibility of the polar lignin and the non-polar matrix PP, three different maleated PP emulsions ME91735 (nonionic PP emulsion), ME42035 (cationic water based emulsion of polyolefin waxes) and PP286 (containing N,N-ethylethanolamine (1-5%)) were used as an coupling agents. The mechanical, thermal, and morphological properties of the blends were investigated. The mechanical properties such as tensile, flexural strength as well as tensile and flexural modulus of the blends increased after treatment of lignin with 5 wt.% emulsion. However, the impact strength slightly decreased than untreated lignin. The morphology of the blends was analyzed using scanning electron microscopy (SEM). Differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), heat deflection temperature (HDT) and dynamic mechanical analysis (DMA) were used to measure the thermal properties of the blends.
