Modified conjugated diene rubber, method and composition thereof |
摘要 |
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 R1, R2, R3 are each independently selected from the group consisting of C1-C12 of alkyl and C2-C12 of alkenyl groups and C6-C12 of aromatic group, and R4 is selected from the group consisting of C1-C12 of alkyl, C2-C12 of alkenyl, C1-C12 of alkoxy groups and C6-C12 of aromatic group; and (b) adding a second modifier having a structural formula (II) after (a),
HO—R5—Y (II)
wherein R5 is selected from the group consisting of C1-C12 of alkylene, C2-C12 of alkenylene, C3-C12 of alicyclic groups and C6-C12 of aromatic group, and Y is selected from the group consisting of oxygen-containing C1-C12 group and nitrogen-containing, C1-C12 group, wherein Y has the oxygen atom or the nitrogen atom directly connected to a carbon atom of R5. |

1. A method for producing a modified conjugated diene rubber, comprising:
(a) reacting an alkali metal ion-containing conjugated diene rubber with a first modifier having a structural formula (I): wherein R1, R2, R3 are each independently selected from the group consisting of C1-C12 of alkyl, C2-C12 of alkenyl groups and C6-C12 of aromatic group, and R4 is selected from the group consisting of C1-C12 of alkyl, C2-C12 of alkenyl, C1-C12 of alkoxy groups and C6-C12 of aromatic group; (b) adding a second modifier having a structural formula (II) after the step (a),
HO—R5—Y wherein R5 is selected from the group consisting of C1-C12 of alkylene, C2-C12 of alkenylene, C3-C12 of alicyclic groups and C6-C12 of aromatic group, and Y is selected from the group consisting of oxygen-containing C1-C12 group and nitrogen-containing C1-C12 group, wherein Y has the oxygen atom or the nitrogen atom directly connected to a carbon atom of R5; (c) adding water before, after, or during the step (b); and reacting a hydrolysis product obtained from the step (c) with the second modifier (II) to produce the modified conjugated diene rubber. |
