A modified conjugated diene rubber is disclosed. A method for producing the modified conjugated diene rubber includes providing an alkali metal ion-containing conjugated diene rubber; and reacting the alkali metal ion-containing conjugated diene rubber with an alkoxysilane to generate the modified conjugated diene rubber, the alkoxysilane being of the structural formula: wherein R, R, Rare each independently selected from a group consisting of oxygen-containing C-Cgroup and nitrogen-containing C-Cgroup, the oxygen-containing C-Cgroup has a carbon atom directly connected to oxygen atom of the alkoxysilane, the nitrogen-containing C-Cgroup has a nitrogen atom directly connected to oxygen atom of the alkoxysilane, and Ris selected from a group consisting of C-Cof alkyl, alkenyl, aryl, and alkoxy.

Conjugated diene rubber modified with polar alkoxysilane, method and composition thereof

A method of forming modified conjugated diene rubber includes (a) reacting an alkali metal ion-containing conjugated diene rubber with a first modifier having a structural formula (I), wherein R, R, Rare each independently selected from the group consisting of C-Cof alkyl and C-Cof alkenyl groups and C-Cof aromatic group, and Ris selected from the group consisting of C-Cof alkyl, C-Cof alkenyl, C-Cof alkoxy groups and C-Cof aromatic group; and (b) adding a second modifier having a structural formula (II) after (a),HO&#x2014;R&#x2014;Y&#x2003;&#x2003;(II)wherein Ris selected from the group consisting of C-Cof alkylene, C-Cof alkenylene, C-Cof alicyclic groups and C-Cof aromatic group, and Y is selected from the group consisting of oxygen-containing C-Cgroup and nitrogen-containing, C-Cgroup, wherein Y has the oxygen atom or the nitrogen atom directly connected to a carbon atom of R.
