According to GlobalData’s company profile on ENEOS, Hydrocarbon redistribution reaction catalysts was a key innovation area identified from patents. ENEOS's grant share as of May 2024 was 43%. Grant share is based on the ratio of number of grants to total number of patents.
A recently granted patent (Publication Number: US11999820B2) discloses liquid crystal polymer particles with specific characteristics, including a high melting point of 270°C or higher, a controlled particle size distribution, and a specific ratio of modal diameter to D50. These particles also exhibit a low dielectric loss tangent and minimal water absorption rate, making them suitable for use in thermosetting resin compositions. The composition includes a combination of the liquid crystal polymer particles and a thermosetting resin, with specific ratios and structural units derived from hydroxycarboxylic acid, diol compound, and dicarboxylic acid.
Furthermore, the patent covers a method for producing the thermosetting resin composition by mixing the liquid crystal polymer particles and the thermosetting resin at a temperature lower than the particles' melting point. The resulting composition can be used to create molded articles such as films, sheets, plates, or electronic circuit boards, including flexible circuit boards. The molded articles exhibit specific characteristics, such as a thin resin film with controlled surface roughness, making them suitable for various applications in the electronics industry. Overall, the patented invention offers a novel approach to creating thermosetting resin compositions with unique properties that can be utilized in a range of electronic applications.
