| 中文摘要: |
| 对分子链端具有较高反应活性的低相对分子质量的二烯类聚合物耐寒助剂进行研究，并考察其在轮胎胶料中的应用。结果表明：耐寒助剂与天然橡胶和通用合成橡胶相容性好，可在胶料密炼或开炼时加入，分散效果好；添加耐寒助剂对胶料的物理性能和耐疲劳性能基本没有影响；耐寒助剂能够降低胶料的玻璃化温度，有利于提高胶料的耐寒性能，适合用于冬季轮胎胶料。 |
| 英文摘要: |
| 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. |
