The main purpose of the present work is to use a renewable material obtained from fruit seed to prepare a reinforced polymer composite with poly(vinyl chloride) (PVC). The characterization of the composites was based on the determination of the molecular motion and of mechanical and thermal properties. The thermal properties were characterized through thermogravimetric analysis (TG) and differential scanning calorimetry (DSC). The mechanical properties were characterized through tensile tests. The molecular dynamic behavior of the polymer matrix was studied by proton spin‐lattice relaxation, using low field nuclear magnetic resonance (NMR). It is shown that the thermal properties do not depend on the filler content, although mechanical properties are improved with the addition of filler. Despite that, no strong interaction between the filler and the PVC matrix could be detected.
