Sažetak
Polystyrene(PS) and polyethylene (PE) blends are used in engineering fields, in constructions, because they have better properties than neat homopolymers.The application of PS and PE polymers is very wide. From this reason the PS/PE blends are very important for plastic wastes recycling from the economical and ecological aspects. The problem of their incompatibility may be improves with compatibilizers. In this paper the influence of PS/HDPE blends compositions with SEBS as compatibilizer, on the morphological structure, rheological and mechanical properties is investigated. The rheological properties are measured with DMA analysis. The relaxation spectra are obtained. Creep relaxations and creep modulus are measured in the creep fatique regime and masters curves are created. Tensil strength, elongation at break and impact strength are determined. On the base of the results obtained and their correlation with SEM microphotographs of investigated systems the correlation between the blend composition, mechanical properties and creep resistance is established and discussed.
