The m-EPR elastomers were added to iPP in 2.5, 5, 10, 15, and 20 vol.%. Torque values, elongation at break and impact strength measured of the iPP/m-EPR1 blends were higher than the iPP/m-EPR2 blends due to higher molten viscosity of m-EPR1 than m-EPR2 copolymer. Slight differences in Young moduli as well as in tensile strength at yield and at break might indicate that tensile properties of iPP/m-EPR blends were not significantly affected by difference in viscosity or molecular mass, miscibility and spherulite size. Optimization diagrams indicated the metallocene m-EPR copolymers are efficient impact modifiers for polypropylene and showed good balancing of mechanical properties in iPP/m-EPR blends"},{"@xml:lang":"sl","#text":"V delu smo preučevali vpliv dveh metalocenskih elastomerov na osnovi etilena/propilena (m-EPR1 in m-EPR2), ki sta se razlikovala v molekulski masi in viskoznosti, na mehanske, reološke in medpovršinske lastnosti. V iPP matrico smo dodali 2.5, 5, 10, 15 in 20 vol.% m-EPR elastomera. Ugotovili smo, da imajo mešanice iPP/m-EPR1 višje vrednosti torzijskega momenta mešanja, raztezka ob pretrgu in udarne žilavosti kot mešanice iPP/m-EPR2 zaradi višje viskoznosti taline m-EPR1 kot m-EPR2 elastomera. Manjše razlike v Youngovem modulu, meji plastičnosti in natezni trdnosti pri pretrgu kažejo, da natezne lastnosti mešanic iPP/m-EPR niso v veliki meri odvisne od viskoznosti ali molekulske mase, mešljivosti in velikosti sferolitov.
