Sažetak
For the selection of the polymer materials for various fields of applications the stability of material under constant load is very important. In this paper the blends of polystyrene (PS) and high density polyethylene (HDPE) with poly[styrene-b(ethylene-co-butylene)-b-styrene] (SEBS) block copolymer were investigated. The investigations were done by DMA analysis. The primary viscoelastic functions storage modulus, (E') loss modulus (E’ ’ ) and loss tangent (tg δ ) were determined. The secondary viscoelastic functions, creep and creep modulus were determined at temperatures 25, 30, 35, 40 and 45 oC. The master curves for reference temperature were created using time temperature superposition, TTS principle. The correlation of the secondary viscoelastic functions with time, temperature and blends compositions was discussed. The results were correlated with morphological structure and mechanical properties obtained in our earlier investigations of the same systems.
