Latest Patents

Oshima's latest patents include a composition comprising an epoxy compound. This innovative composition features an alicyclic epoxy compound formed through an epoxidation reaction of a polymerized cyclo olefin compound. The resulting cured epoxy resin exhibits excellent heat resistance, outdoor durability, and water resistance. These attributes are due to the absence of ether units derived from the ring-opening of epoxy groups and hydroxyl groups from an initiating agent. Another significant patent involves compositions of polyether compounds and epoxy compounds. This patent discloses a composition obtained by the addition copolymerization of a mixture of 4-vinylcyclohexene-1-oxide and a compound with at least two epoxy groups. The invention also relates to processes for producing these compositions, which demonstrate a higher softening temperature compared to those produced by polymerization of only 4-vinylcyclohexene-1-oxide.
