Title: Rafael E Guerra: Innovator in Polymer Technology
Introduction
Rafael E Guerra is a notable inventor based in Lake Jackson, TX (US). He has made significant contributions to the field of polymer technology, holding a total of 3 patents. His work primarily focuses on the removal of contaminants from solutions, particularly metal contaminants, using innovative polymer materials.
Latest Patents
One of Guerra's latest patents involves the removal of metals from solutions. This patent describes the use of particles, fibers, or filaments of ethylene/carboxylic acid copolymers or terpolymers, especially in highly porous or microporous forms. These materials are effective in removing contaminants from both aqueous and organic liquids. The porous polymers have a surface area/weight ratio of at least about 0.5 m²/gm, making them useful alone or in conjunction with known ion exchange resins, such as polyacrylic acid crosslinked with divinylbenzene. Another significant patent by Guerra focuses on the polymerization of olefins in the presence of chromium-containing catalysts. This method improves the deposition of chromium onto the inorganic oxide support in the vapor phase, resulting in polymers with higher molecular weights compared to those produced using conventional methods.
