Title: Shigeru Sasaki: An Innovator in Hydrogenated Copolymers
Introduction
Shigeru Sasaki is a prominent inventor based in Tokyo, Japan, renowned for his extensive contributions to the field of polymer science. With a remarkable total of 29 patents to his name, Sasaki has been instrumental in advancing technologies involving hydrogenated copolymers and their applications in various industries.
Latest Patents
One of Sasaki's latest patents is centered around a hydrogenated copolymer and the composition containing it. This innovative hydrogenated copolymer is derived by hydrogenating an unhydrogenated copolymer, which includes conjugated diene monomer units and vinyl aromatic monomer units. The unique features of this hydrogenated copolymer include a vinyl aromatic monomer unit content ranging from more than 40% by weight to less than 95% by weight. Notably, at least one peak of loss tangent (tan δ) is observed in a dynamic viscoelastic spectrum, which is obtained with respect to the hydrogenated copolymer at temperatures between -10 to 80°C. Furthermore, the differential scanning calorimetry (DSC) chart related to the hydrogenated copolymer reveals substantially no crystallization peak attributed to the copolymer block in the temperature range of -20 to 80°C.
