Description
  • Cílem této práce je porovnat reologické chování tří odlišných metalocenových typů polypropylenů připravených reaktivním vytlačováním. Tokové chování bylo následně popsáno molekulárními konstitučními rovnicemi (XPP, PTT-XPP) a bylo překvapivě zjištěno, že zkoumané vzorky polypropylenů neobsahují větvení typu H. (cs)
  • The aim of this contribution is to compare rheological behavior of three different samples of metallocene catalyzed polypropylene [virgin (linear) metallocene polypropylene (mPP), and (branched) mPPs prepared through reactive processing with (0.01 wt %) and without peroxide]. For their rheological description in different flow situations (shear and elongational) the eXtended Pom-Pom (XPP) and PTT-XPP models were used. A rotational rheometer (ARES 2000) with the SER Universal Testing Platform were used for the measurement of dynamic data (storage G' and loss G'' moduli) and uniaxial extensional viscosity. It was shown that both processed (branched) mPPs (with and without peroxide) exhibit distinct behavior in uniaxial extensional viscosity (appearance of strain hardening) in comparison to the virgin (linear) mPP. The XPP and PTT-XPP models proved their usefulness for a branching level quantification based on the measurements of steady shear and elongational viscosities. On the other hand
