Latest Patents

One of his latest patents is titled "Selective admixture of additives for modifying a polymer." This invention involves modifying the molecular weight of solid polymers, particularly polyolefins, by adding organic peroxides or other free radical generators in a first reaction zone. The polymer is then melted, followed by the addition of secondary additives such as antioxidants and light stabilizers in a second reaction zone, where intense mixing occurs. This method improves the color and odor characteristics of the polymer compared to concurrent admixture of all additives. Another significant patent is "Additive to improve polymer clarity and viscosity." This composition includes a polyolefin and a hydroxylamine, which enhances clarity and reduces viscosity. The process involves visbreaking the polyolefin in the presence of hydroxylamine, leading to improved material properties.
