Latest Patents
Kato Hiroshi holds a patent for "Block copolymers and uses thereof." This patent describes a styrenic block copolymer that consists of one or more polymer blocks A and one or more polymer blocks B. The 'A' block is a poly(vinylaromatic) block with a molecular weight greater than 5 kg/mol, while the 'B' block has a molecular weight exceeding 15 kg/mol. The 'B' block comprises polymerized 1,3-diene units and vinylaromatic units, with the polymerized vinylaromatic units representing 5-40 wt. % of the overall weight of the block B. The polymerized 1,3-diene units consist of more than 80 wt. % of polymerized isoprene units, where 45-80 mol % are 1,4-isoprene addition units. The blocks A and B represent from >5 to <40 wt. % and >33 to <95 wt. %, respectively, relative to the overall weight of the block copolymer. These polymers exhibit physical properties that make them particularly valuable.
