  • Modified polymethylhydrosiloxane, modified high-cis conjugated diene polymer, and manufacturing method for the same, and rubber composition and tire using the same
    Patent number: 10889659
    Abstract: The present disclosure provides a modified polymethylhydrosiloxane, a modified high-cis conjugated diene polymer, and a manufacturing method for the same, and a rubber composition and a tire using the same. The manufacturing method for the modified high-cis conjugated diene polymer comprises: performing a polymerization reaction to form a high-cis conjugated diene polymer; and making the high-cis conjugated diene polymer react with a first modifier, and then react with a condensation accelerator and a second modifier to generate a modified high-cis conjugated diene polymer; wherein the modified high-cis conjugated diene polymer has over 97% of cis-1,4 structure. The second modifier comprises a compound represented by the following formula (1).
