Rheological behavior of poly(l-butene)/wood composites

Abstract

The work deals with the influence of content of the untreated wood flour filler (natural pine wood) on rheological behavior of blends with poly(l-butene) matrix. Therefore the blends with 5, 10, 15, 20, 30 and 50 % of wood flour were prepared in microcompounder. The rheological behavior was studied in oscillatory shear regime. Cole-Cole plot was used for determination of differences in molecular weight and distribution. It was found that low content of the wood flour acts as a lubricant agent and decreases zero shear viscosity. On the contrary, increasing content of the wood flour has an opposite effect.
