摘要

In the present study,the composites of polypropylene and wood were prepared.The experimental material comprised two most common Polish timber species pine wood (Pinus sylvestris L.) as a softwood species and oak wood (Quercus sp.) as a hardwood species.The size of wood sawdust ranged from 0.5 to 1.0 mm.Two types of lignocellulosic materials were used in the experiments described:wood without any previous chemical treatment and wood after its mercerization (i.e.activated with NaOH).In addition the polypropylene-wood composite containing a block copolymer,i.e.styrene-ethylene-butylene-styrene (SEES) was also obtained.The objective of this study was to evaluate the resistance of different kinds of polypropylene-wood composites to fungal decay.Weight losses and temporary tensile strength of composite samples after the mycological test were determined.
