The present invention is concerned with a method for adding additives to a polyolefin melt or to a polyolefin solution by means of a solution or dispersion of additives in n-alkane. In particular, the present invention relates to such a method that ensures a homogeneous distribution of the additive in the polyolefin melt or the polyolefin solution and cost savings. Furthermore, the present invention is concerned with a solvent based polyolefin recycling process comprising said method for adding additives in n-alkane. Furthermore, the present invention concerns with a process for producing polyolefin pellets comprising carrying out said method for adding additives in a melt extruded polyolefin.

The present invention is concerned with a process for separating a polyolefin from a stream comprising a polyolefin of a solvent based recycling (SbR) process. In particular, the present invention relates to such a process that ensures thermal stability of the recycled polyolefin, in particular during the devolatilization steps for removing the solvent. Furthermore, the present invention is concerned with a polyolefin obtainable from such a process.
The present invention relates to a composition comprising 70 to 95 wt.-% of a high isotactic homopolymer of propylene, more than 2.5 to less than 30 wt.-% of a cyclic olefin polymer composition, and 0.1 to 2.5 wt.-% of a random propylene copolymer compatibilizer. The present invention is, furthermore, directed to a film comprising the polypropylene composition. Apart from that, a biaxially oriented film comprising the polypropylene composition and a capacitor are provided.
