Latest Patents

Hida’s listed patent, “Resinous Composition and Sheet Product Therefrom,” describes a blend of a thermoplastic olefin resin and an acrylonitrile-styrene-alkyl acrylate copolymer. The initial blend had inferior interdispersibility compared with vinyl chloride resin combined with a plasticizer. Adding an epoxy resin improved the interdispersibility.

The patent specifies an epoxy resin selected from epoxidized diene block copolymers. These copolymers contain blocks derived from vinyl aromatic and conjugated diene monomers, with residual diene groups that have been epoxidized or partly hydrogenated. The resulting composition is presented as a potential substitute for vinyl chloride compounds and as a material for related products, including sheets.

Career Highlights

Hida’s documented patent contribution focuses on polymer formulation and improving the compatibility of resin components. The invention’s stated aim is to provide a useful alternative to vinyl chloride-based materials.
