Sažetak
For the selection of the polymer materials and polymer blends for various fields of applications, the stability of those materials against ageing is very important. In physical ageing the changes of structure and properties are consequences of physical processes, which include processes involved in molecular relaxation or rearrangements under the influence of temperature, time and constant stress (1). It is specially evident in multicomponent polymeric system, copolymers (2) and polymer blends (3) and are very important for their selection for structural or engineering applications. In this paper the review of physical ageing of: polyurethane elastomers (PUR) under thermal treatment and high impact polystyrene (PS-HI), styrene-butadiene-styrene (SBS) and their blends (PS-HI +SBS) under the constant stress in function of temperature and time were done.
