Latest Patents
Keiichi Toda's latest patents include two notable inventions. The first is a modified rubber and the process for producing it. This invention relates to a modified rubber that has a specific structure altered with a compound containing two or more epoxy groups. The process involves copolymerizing a vinylaromatic hydrocarbon and a conjugated diene using solution polymerization with an organolithium initiator. The resultant copolymer is then modified with the epoxy compound. Additionally, this invention encompasses a modified-rubber composition that combines raw rubber with silica, leading to applications in rubber vibration isolators and footwear articles.
The second patent is for a heat-stabilized block copolymer composition. This composition consists of a block copolymer made from a monoalkenyl aromatic compound and a conjugated diene compound. The weight percentage of the monoalkenyl aromatic compound ranges from 5-95% of the total weight of the block copolymer. By incorporating two or more specific phenolic stabilizers, this block copolymer composition demonstrates excellent heat stability, minimizes gel-like material formation, and maintains a superior color tone.
