Sažetak
Among thermoplastics the polypropylene is outstanding with respect to its attractive combination of low cost, low weight, heat distortion temperature above 100°C, and extraordinary versatility in terms of properties and applications. With the appropriate modification it is possible to improve the existing properties of the PP, or even obtain the new ones. As a result of its originally superior properties, the PP is commonly used in medical purposes, where it has to undergo the process of sterilization beforehand. The sterilization of the PP in medicine is most often being carried out with low dose of gamma irradiation, which can influence the changes of properties of both the polymeric matrix and modifiers. Therefore the purpose of our research work was to determine the structure-mechanical properties relationships of unirradiated an gamma irradiated PP composites with talc filler and poly-(styrene-b-ethylene-co-butylene-b-styrene) block copolymer (SEBS) or SEBS grafted with maleic anhydride (SEBS-g-MA) as elastomeric modifiers, as well as of corresponding binary composites and blends. Unirradiated and gamma irradiated composites and blends were characterised by wide angle X-ray difraction, optical microscopy, scanning electron microscopy, FTIR spectroscopy, tensile measurements and measurements of notched impact strength. The effects of composition and gamma irradiation on the properties of the PP composites and blends are discussed in the article with emphasis on study of the stabilizing effect of talc in irradiated PP composites.
