A novel carbon nanotube powder containing carbon nanotubes which have a roll-like structure, also novel carbon nanotubes having a roll-like structure, novel processes for the production of the carbon nanotube powders and of the carbon nanotubes, and their use as an additive or substrate for various applications are described.

Carbon nanotube powder, carbon nanotubes, and processes for their production

A method for separating electrolyte-containing water from an organic phase by means of permeation on a hydrophobic separating means. The permeated organic solution is substantially depleted in water and the retained water is enriched with electrolytes.

Method for separating an organic phase from an electrolyte-containing aqueous and organic phase

Rubber-free copolymers of unsaturated monomers selected from the group comprising styrenes and vinyl cyanides are disclosed. The copolymers that contain 65 to 80 wt. %, of styrene and 20 to 35 wt. % of acrylonitrile are characterized in their low content of residual monomers and improved physical properties. Also disclosed are a process and a device for the preparation of these copolymers.

Copolymers, devoid of rubber, with low residual monomer content and a method and device for producing the same

A process for concentrating polymers by evaporation is disclosed. The process entails (i) obtaining a mixture containing a polymer and volatile component, the volatile components being present in the mixture at an amount less than 20 wt. % relative to the weight of the mixture, and (ii) introducing the mixture in a downward direction under pressure through a plurality of nozzles arranged vertically and next to one another into a degassing container to form an extrudate. The volatile component contains at least one of residual monomers, oligomers and solvents, and the throughput of the mixture per nozzle is 0.3 to 2 kg/h. The vapor pressure of the volatile component of the extrudate is more than 2.5 bar, and the absolute pressure in the degassing container is 50 to 5000 Pa. The polymer prepared by the process is characterized in that it contains volatile components in an amount of less than 300 ppm.

Process for separating volatile components from polymers

Modified polyurethanes based on polyurethane reactive systems composed of at least one organic polyisocyanate and a polyol formulation, which additionally contains at least one polymer modifier and at least one filler are prepared. These modified polyurethanes are useful in the production of electroplated/metallized molded articles.
