Beschreibung
Zusammenfassung:	To provide 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.SOLUTION: The method includes making a 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).SELECTED DRAWING: None 【課題】変性ポリメチルヒドロシロキサン、変性高シス共役ジエンポリマー、およびそれの製造方法、ならびにそれを使用するゴム組成物およびタイヤを提供する。【解決手段】高シス共役ジエンポリマーを第１変性剤と反応させ、その後縮合促進剤および第２変性剤と反応させて変性高シス共役ジエンポリマーを生成する工程とを含み；ここで、変性高シス共役ジエンポリマーは、９７％超のシス−１，４構造を有する。第２変性剤は、次式（１）で表される化合物を含む。【選択図】なし
