Publication number: 20030047831Abstract: In a method for granulating thermoplastic polymers, in particular thermoplastic polyolefins, the polymer powder prepared in the polymerization reactor is melted and homogenized in an extruder, then forced through an extrusion die and granulated. In accordance with the invention, the polymer powder is subjected to heat treatment before introduction into the extruder, resulting in the introduction of the polymer powder into the extruder being carried out at an elevated powder temperature. The invention is particularly suitable for the granulation of polyethylene or polypropylene.Type: ApplicationFiled: September 13, 2002Publication date: March 13, 2003Inventors: Michael Witt, Rainer Anderlik, Jurgen Hofmann, Thomas Kessler, Farid Rizk, Wolfgang Bickel

Patent number: 5735830Abstract: A polymer material (6) is formed from a first polyethylene component (1) having a low density (VLDPE) which is silane-grafted with an organic silane (3) in combination with organic peroxide (4) and is cross-linked through storage in a damp environment and/or in water. The polymer material (6) can be processed into medical instruments under dry conditions prior to cross-linkage. After cross-linkage the medical instruments made from the polymer material (6) exhibit a high degree of transparency, are non-buckling and flexible. The polymer material (6) is produced in an extruder, preferentially in a double-worm extruder.Type: GrantFiled: July 11, 1996Date of Patent: April 7, 1998Assignee: Willy Rusch AGInventors: Hans-Gerhard Fritz, Rainer Anderlik, Armin Singvogel, Michael Heider
