Compatibilization of PP/PE blends and scraps with Royalene: Mechanical properties, SAXS, and WAXS
Original language description
PP/PE 93/7 model virgin blends and recycled scraps were compatibilized with Royalene (EPDM/PE 65/35 blend) and mechanically tested. No differences in impact and tensile properties between them were found. However, the tensile-impact strength increased almost twice with 10%-compatibilized sample in comparison with uncompatibilized ones. The yield stress of blends containing 10% Royalene decreased to 75-80% of the original value. The elongation at break and elongation at yield do not depend on the compatibilizer concentration. The compatibilizer does not influence the degree of crystallinity (WAXS data) of the blends either. Vickers microhardness is in good agreement with Tabor's relationship. The differences between long periods of HDPE in Royalene andLDPE in PP/PE blends proved PE/EPDM interaction. The interaction plays a key role in the toughening of PP/PE blends.

Kompatibilizace směsí a recyklátů PP/PE s přídavkem Royalene: Mechanické vlastnosti, SAXS a WAXS
Czech description
Modelové a recyklované směsi PP/PE 93/7 byly kompatibilizovány přídavkem Royalene (směs EPDM/PE 65/35) a mechanicky testovány. Nebyly nalezeny rozdíly v houževnatosti a pevnosti mezi modelovými směsmi a recykláty. Kompatibilizací (10%) se houževnatost zvyšuje téměř dvakrát, mez kluzu se snižuje na 75-80%,což koreluje s hodnotami mikrotvrdosti. Tažnost, deformace na mezi kluzu ani krystalinita nezávisí na koncentraci kompatibilizátoru. Naměřená Vickersova mikrotvrdost dobře vyhovuje Taborovu vztahu. Rozdíly v hodnotách dlouhé periody HDPE v Royalenu a LDPE ve směsích PP/PE dokazují interakci mezi PE a EPDM, jež je klíčová pro zvýšení houževnatosti směsí PP/PE.
