Sažetak
Due to their good properties polymer materials are present in almost all area of human life. The need for recycling of polymer materijals has been recognized especaially as a result of growing awareness of environmental pollution by polymer waste. During processing and reprocessing at higher temperatures the polamer materials is exposed to thermal, oxidative as well as shear induced degradation. Therefore, the physical and mechanical characteristic such as flow behaviour, tensile strength, and elongation or impact strength differ of those of initial material. The change in melt flow rate (MFR) can be used to study thermal degradation of polymer materials in processing. The papaer deals with determination of MFR of wood-polypropylene) composite regenerate of different cycle of reprocessing. Since the melt behaviour of processed material is sensitive to the changes in molecular structure, knowlwdge of the MFR is useful for asssessing the reprocessibility of polymer waste material.
