Latest Patents

Matsumoto's latest patents showcase his cutting-edge research in olefin copolymers and films and sheets. One of his notable innovations is a novel olefin copolymer composed of three critical components: a cyclic olefin, an aromatic vinyl compound, and an aliphatic α-olefin with a carbon chain length ranging from 2 to 20. The specific composition of this copolymer features component A accounting for 0.1 to 30 mol %, component B for 0.1 to 49.9 mol %, and a total for components A and B of 0.2 to 50 mol %. This copolymer exhibits a glass transition temperature (Tg) of less than 60 °C, which makes it a suitable alternative to soft polyvinyl chloride due to its elasticity and transparency.

In another innovative patent, Matsumoto has developed catalysts for the polymerization of olefins, alongside processes for producing olefin and styrene polymers. These catalysts consist of a transition metal compound and a selection of materials such as clay or silane compounds, enhancing polymerization activity while reducing the need for large quantities of aluminoxane. This innovation results in the production of high-quality polymers with minimal metallic residue, making the method suitable for industrial applications.
