Sažetak
For the selection of the polymer materials and polymer blends for various fields
of applications, dynamic-mechanical properties, the primary viscoelastic functions as well
as the stability of materials on different loads are very important.
Since polymer materials are viscoelastic, their mechanical properties are dependent on temperature and time.
The dynamic-mechanical properties of high-impact polystyrene, (PS-HI) and blends of PS-HI and styrene-butadiene-styrene block
copolymer, (SBS) were investigated. In the conditions of dynamic-mechanical
load, the investigated systems will have different behaviours due to the various
content of the hard phase, polystyrene and soft phase, polybutadiene. The investigations
were done by DMA analysis. The primary viscoelastic functions were determined. The influence of the constant stress on
the strain and moduls at various temperatures was examined. The effects of the time
on moduls changes was obtained by generated the master curves. The viscoelastic functions and the
stability on the constant load, the changes on the moduls with time and
temperature depend on the amount of polystyrene in examined copolymers and blends. This investigations give the possibility of predicting useful
life time of materials.
