Title: Makoto Okamoto: Traceable Vinyl Acetate and Polymer Innovation.
Introduction
Makoto Okamoto is an inventor associated with Pasadena, Texas, and Kuraray Co., Ltd. His work includes a patent concerning traceable vinyl acetate and polymers made from it. The available information identifies 1 patent associated with him.
Latest Patents
Okamoto’s listed patent is titled “Vinyl Acetate, Vinyl Acetate Polymer, and Vinyl Alcohol Polymer.” It addresses the challenge of providing vinyl acetate that can be traced, along with a polymer containing that vinyl acetate and a vinyl alcohol polymer produced by saponifying the polymer.
The disclosed solution uses vinyl acetate with a carbon-14-to-total-carbon ratio of at least 1.0 × 10⁻ⁿ, where the exponent is not fully specified in the supplied description. The vinyl acetate serves as a monomer unit in a polymer, which can then be saponified to produce a vinyl alcohol polymer.
Career Highlights
The patent reflects Okamoto’s work on polymer materials and traceability. Its described approach connects the carbon-14 content of vinyl acetate with the identification of the resulting polymer materials.
Collaborations
Okamoto is associated with Kuraray Co., Ltd. His listed coworker is Keishi Hachiya.
Conclusion
Makoto Okamoto’s listed patent focuses on traceable vinyl acetate and its use in producing vinyl acetate and vinyl alcohol polymers, highlighting a materials innovation associated with Kuraray Co., Ltd.
