Title: David L Beach: Innovator in Polymer Chemistry
Introduction
David L Beach is a notable inventor based in Kingwood, TX (US). He has made significant contributions to the field of polymer chemistry, holding a total of 16 patents. His work primarily focuses on developing advanced materials with enhanced properties.
Latest Patents
One of his latest patents is titled "Process for making MVTR resin." This invention is directed towards producing a resin that, when formed into a film, exhibits excellent gas barrier and moisture barrier properties. The resin boasts a relatively high molecular weight distribution, preferably above 6, and demonstrates excellent processability and extrudability. The production process utilizes a cyclopentadienyl chromium compound, specifically a mono CpCr compound, on a silica support. A particularly preferred catalyst for this invention comprises pentamethylcyclopentadienyidimethylchromiumpyridine, which is used in a slurry polymerization process.
Another significant patent is related to "Olefin polymerization using aluminoxane/chromium catalysts." This method involves controlling the molecular weight distribution of a polyalpha-olefin during polymerization by adjusting the aluminoxane to chromium ratio in the polymerization catalyst. This innovative approach allows for precise adjustments in the molecular weight distribution of the resulting polymers.
