Latest Patents

Yasuda holds a patent for a process for producing a diolefin polymer or copolymer. This process involves polymerizing 55-100 wt % of a conjugated diolefin with 0-45 wt % of an aromatic vinyl compound in a hydrocarbon solvent. The use of specific initiators, including a reaction product between secondary amine compounds and organic lithium compounds, is a key aspect of this invention. The resulting rubber composition, which contains at least 30 wt % of the diolefin polymer or copolymer, exhibits excellent properties such as abrasion resistance, high tensile strength, and low rolling resistance. This makes it particularly suitable for low fuel consumption tires.
