THERMAL CHARACTERIZATIONS OF THE POLYOLEFIN/NATURAL POLYMERS BLENDS

摘要

The aim of this work was to obtain of the information referring to the thermal processes of the composite materials having natural polymers. A comparatively study of thermo oxidative behavior of the some polyolefin/wood flour (WF) and lignin (L) blends with variable composition were made. It was remark that materials with a higher percent of the natural polymer present a reduced thermal stability comparatively with the matrix. One can also observed that the introduction as filling materials of the lignin leads to composite materials much stable for thermal point of view than those containing wood sawdust.
