With a total of 4 patents to his name, Murakami's work has garnered attention for its practical applications and advancements in material science.

Latest Patents

Murakami's latest patents include an alkyl-modified carboxyl group-containing copolymer and a thickener containing said copolymer. This copolymer is designed to create a neutralized viscous liquid that exhibits excellent dispersibility in water. It maintains a stable viscosity regardless of electrolyte addition and demonstrates high transparency in such conditions. The copolymer consists of 100 parts by mass of a (meth)acrylic acid, 1.5-4.5 parts by mass of a (meth)acrylic acid alkyl ester with an alkyl group containing 18-24 carbon atoms, and a small amount of a compound with multiple ethylenically unsaturated groups. Additionally, it includes 1.5-4.5 parts by mass of a nonionic surfactant.

Another notable patent involves a method for producing a carboxyl group-containing polymer composition. This method ensures excellent dispersibility in water, storage stability, and transparency of the resulting neutral viscous solution. The composition comprises a copolymer of monomers that include an α,β-unsaturated carboxylic acid and a compound with at least two ethylenically unsaturated groups. The nonionic surfactant is introduced during the polymerization process when the degree of polymerization reaches 70 to 100%.
