Latest Patents

Among Hagerty's latest innovations, two notable patents stand out. The first is focused on **high activity polyethylene catalysts**, specifically designed to produce bimodal or trimodal polymers. This catalyst composition utilizes a silica carrier treated with a dialkyl magnesium compound, a halogen-containing compound, and titanium tetrachloride, leading to the formation of an effective catalyst precursor. This precursor is then activated with dimethylaluminum chloride, resulting in polymer products that exhibit multimodal molecular weight distributions. This advancement presents a remarkable improvement over unimodal distributions typical of previously used catalyst precursors.

The second patent outlines a **process and system for preventing pressure tap fouling in tandem**. This innovation addresses the issue of fouling in pressure taps within a gas phase fluidized bed polymerization reactor. By introducing a small amount of water directly to the pressure taps of the first reactor, Hagerty's system successfully avoids sheeting during the production of polyolefins in downstream operations. This method enhances efficiency and maintains the integrity of the polymerization process, showcasing Hagerty's innovative approach to problem-solving in industrial settings.
