| Abstract: |
| The cold-resistant additives of low relative molecular weight diene polymer with high
reaction activity at molecular chain end were studied，and their application in tire compound was investigated.
The results showed that the cold-resistant additives had good compatibility with natural rubber and general
synthetic rubber，and could be well dispersed using either inner mixing or open-mill mixing process. Addition
of cold-resistant additives had little effect on the physical properties and fatigue resistance of the compound.
The cold-resistant additives could lower the glass transition temperature of the compound and improve the
cold-resistance，which was suitable for winter tire compound. |
