Title: Haruyoshi Kitahara: Innovator in Thermoplastic Resin Compositions
Introduction
Haruyoshi Kitahara is a notable inventor based in Ohtake, Japan. He has made significant contributions to the field of thermoplastic resin compositions, holding a total of four patents. His work focuses on enhancing the impact resistance and weather resistance of resin materials.
Latest Patents
Kitahara's latest patents include innovative graft copolymer resins. These resins are prepared by graft polymerizing a vinyl compound onto a composite-structured acrylic rubber. The rubber particles consist of a core made from diene rubber, which is treated with an acid group-containing copolymer latex. The outer layer is formed from an acrylate polymer that has a crosslinked structure, achieved through the combined use of a graft-linking agent and a cross-linking agent. This unique composition allows for blending with rigid thermoplastic resins in specific proportions. The resulting resin composition not only imparts a good gloss to molded articles but also retains excellent impact and weather resistance.
