Latest Patents
Ogasa's latest patents include a process for preparing polymers using copper compounds. One of his key inventions is a plastic foam material composed of a polyolefin-based resin composition. This innovative material consists of specified amounts of polypropylene-based resins and polyethylene-based resins, ranging from about 20 to about 65 weight percent of a cross-linked portion. The cross-linked portion is made up of approximately 55 to 95 weight percent of cross-linked polypropylene and 5 to 45 weight percent of cross-linked polyethylene. The degree of cross-linkage can be determined using a xylene extraction technique. Additionally, the plastic foam material may incorporate specified amounts of a cross-linking agent and an organic thermodecomposition foaming agent. This foaming agent decomposes at high temperatures, resulting in a plastic foam material that exhibits superior adherence properties and minimizes surface deformities such as swelling, shrinkage, and wrinkling. A method for producing this plastic foam material is also disclosed in his patents.
