The coloration of plastics is an important quality feature of medical devices, and it is most frequently done by using masterbatches. This study investigates the influence of masterbatches with different carrier resins on the impact resistance and the morphology of an acrylonitrile-butadiene-styrene (ABS)/styreneacrylonitrile (SAN) blend. The experimental results were compared with thermodynamical models based on Hansen and Flory-Huggins theory. The models, as well as notched impact testing, indicated strong immiscibility and incompatibility when using a masterbatch carrier based on polystyrene (PS). Immiscibility was confirmed by morphology studies that revealed the formation of PS-droplets with increasing masterbatch content. Masterbatches based on ABS and SAN showed no significant impact and theoretical calculations were in good accordance with mechanics and morphology. The proposed theoretical calculation of solubility between blend partners potentially allows a prediction for selecting a suitable masterbatch carrier.

, this paper examines the effects of EUA price variations on the electricity mix. We focus on the German electricity market, since it is one of the most important EU electricity markets. In this context, we formulate a simulation model for the scenario years 2011, 2020, and 2030 as MCP and compute results utilizing GAMS. Our results indicate that the ability of EUAs to influence the production mix starts at EUA price levels that have not often been observable in the EU ETS until today (i.e. > €25-35/ton) and that in order to reach Germany's future RES-E target shares, EUA price levels of €40 (2020) and €45 (2030) are sufficiently high enough according to our model. Motiviert durch die Einführung der dritten EU ETS Handelsperiode in 2013, beschäftigt sich dieser Artikel mit den Effekten von EUA Preisschwankungen auf die Zusammensetzung der Stromerzeugung. Wir konzentrieren uns hierbei auf den deutschen Elektrizitätsmarkt als wichtigsten und größten Elektrizitätsmarkt innerhalb der EU. In diesem Zusammenhang erstellen wir ein auf MCP basierendes Simulationsmodell für die Jahre 2011, 2020 und 2030 und ermitteln die Ergebnisse mittels GAMS. Unsere Ergebnisse zeigen, dass EUAs erst ab einem Preis von ca. €25-35/Tonne CO 2 den Elektrizitätsmix wesentlich beeinflussen. Des Weiteren ist ein CO 2 Preisniveau von €40 (2020) bzw. €45 (2030) notwendig, um die deutschen Ziele in Folge des EEG zu erreichen.
