He has made significant contributions to the field of polymer science, particularly in the development of innovative materials and catalysts. With a total of 3 patents to his name, Harris has demonstrated a commitment to advancing technology in his industry.
Latest Patents
Harris's latest patents include the creation of resin-coated glass articles. These articles are designed to enhance safety by reducing shatter and scatter when glass breaks. The resin coating, made from copolymers of ethylene and 2-norbornenes or terpolymers of ethylene, 2-norbornenes, and 1-butene, is particularly beneficial for bottles used in bottling carbonated beverages. This innovation helps prevent dangerous flying glass in the event of a drop or explosion.
Another significant patent by Harris involves high-efficiency catalysts for olefin polymerization. These catalysts are prepared by reducing transition metal compounds with an organometallic compound. By reacting excess organometallic compound with a deactivation agent, such as hydrogen chloride, before activation with organoaluminum compounds, catalyst efficiencies of up to 700,000 grams of polyethylene per gram of transition metal have been achieved at reactor pressures as low as 50 psig.
