Regenerative Energie
Up to now, only a few publications reported improvement of processing properties by addition of commercial organoclays to recycled PET. Nevertheless, moderate degrading reactions were detected during the melt compounding process.
With a view to reduce the mentioned degradation and to increase delamination in the system, the selected commercial organoclays were additionally modified. The principle of the treatment consists in silanization of clay hydroxy groups by the selected silane in aqueous-methanolic environment. The bonded functional groups can facilitate chemical or physical interaction of the filler with the polymer matrix and eliminate the hydrolysis of PET by the silicate hydroxyl groups. In this presentation, recycled PET-clay nanocomposites using commercial as well as modified organoclays are analysed by rotational rheometry and the effects of silicate modification on the melt flow properties are discussed.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
