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, the patent discloses conjugated diene-based impact modifiers for these polymers, resulting in impact-resistant blends that are particularly useful for packaging materials requiring high thermoformability, processability, and excellent barrier properties.

Another significant patent by Williams 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, leading to polymeric metallo-carboxylates with a three-dimensional cross-linked structure. The metallocarboxylates produced exhibit improved characteristics by neutralizing some carboxyl groups with a basic reagent before condensation, enhancing the overall performance of the elastomers.
