Latest Patents
One of his latest patents is titled "Barrier resins and impact modifiers therefor." This invention involves polymers that exhibit low permeability to gases and vapors while maintaining high heat stability and creep resistance. The polymers are created through a novel method of polymerizing acrylonitrile, a vinylidene aromatic monomer such as styrene, and an olefinic ester like methyl methacrylate. Additionally, he has developed conjugated diene-based impact modifiers for these polymers, resulting in impact-resistant blends that are particularly useful for packaging materials requiring high thermoformability, excellent barrier properties, and heat stability.
Another significant patent is "Preparation and use of acrylic ionomer elastomers." This invention describes a process where an alkyl acrylate polymer is cured by condensing carboxyl groups with a polyvalent metal oxide. The resulting polymeric metallo-carboxylates are characterized by a three-dimensional cross-linked structure. Improved metallocarboxylates are produced by neutralizing some carboxyl groups with a basic reagent before condensation, enhancing the material's properties.
