Latest Patents

Among Tanaka's notable inventions is a **soluble and curable fluorine-containing copolymer**. This novel copolymer comprises 25-75 mol % of chlorotrifluoroethylene, 10-70 mol % of a vinyl or isopropenyl ester of fatty acid, and 3-40 mol % of allylglycidyl ether. It may also include additional comonomers, such as acrylates. This copolymer demonstrates favorable fluororesin characteristics, offering solubility in various organic solvents and curing properties when exposed to compounds that react with epoxy groups. The resulting coating liquid produces a hard, stable, and transparent film on both metal and glass surfaces.

Another noteworthy invention is the **optical fiber having a polymethacrylate core and fluoro-copolymer cladding**. In this step-index type optical fiber, the core material consists of poly(methyl methacrylate) or a copolymer of methyl methacrylate with other methacrylates or acrylates. The cladding utilizes a copolymer of vinylidene fluoride with hexafluoroacetone, which ensures strong adhesion to the polymethacrylate core. This innovative design results in a copolymer that is low in crystallinity, high in transparency, and possesses a softening temperature exceeding 100°C, making it suitable for extrusion alongside poly(methyl methacrylate).
