Latest Patents
One of his latest patents is a process for pelleting ultra-high molecular weight polyethylene. This innovative method involves compacting pulverulent ultra-high molecular weight polyethylene, either alone or in a mixture with other polyethylenes, into extrudates through extrusion agglomeration. The process occurs under pressure at temperatures ranging from 100°C to 150°C, with average residence times in the die of 2 to 40 seconds and a compression ratio of 1:5 to 1:15. The resulting extrudates are then divided into pellets. Another significant patent is for the preparation of metal nitrates. This process involves creating aqueous metal nitrate solutions by dissolving the metal in nitric acid. The formation of ammonium nitrate is suppressed, and the dissolution process is accelerated by adding nitrous acid or a substance that forms nitrous acid.
