Latest Patents

Margaret Kerr's latest patents include the development of supported metallocene catalysts and processes for their use in isotactic polymerization of a Cethylenically unsaturated monomer. The supported catalysts consist of a particulate silica support, an alkyl alumoxane component, and a metallocene catalyst component. The support features an average particle size of 10-50 microns, a surface area of 200-800 m/g, and a pore volume of 0.9-2.1 milliliters per gram (ml/g). The incorporation of alumoxane onto the support is designed to achieve a weight ratio of alumoxane to silica of at least 0.8:1. The metallocene is present in an amount of at least 1 weight percent of the silica and alumoxane, following a specific formula that includes various structural components.

Another significant patent involves the process of preparing silica-supported catalysts. This method entails using a support material comprising silica particles impregnated with an alumoxane co-catalyst. The co-catalyst is strategically disposed within the internal pore volume of the silica and is contacted with a dispersion of a metallocene catalyst in an aromatic solvent. The process is conducted at a temperature of about 10°C or less, allowing the metallocene to become reactively supported on the alumoxane-impregnated silica particles.
