| 摘 要： | 研究了镍系高顺式１，４－聚丁二烯与钴系高间同１，２－聚丁二烯二元共湿物的生胶性能和硫化胶性能。结果表明，随着共混胶中间同１，２－聚丁二含量分数为４％时，共混胶不冷流。当间同１，２－聚丁二烯质量分国８％时，共混胶加工性能与ＢＲ９０００接近，硫化胶３００％定伸应力较ＢＲ９０００提高３ＭＰａ，伸长率为４６０％并显示出较好的综合性能。

| Abstract: | Row rubber and vulcanizate properties of blends of Nickelcatalyzed high cis1,4polybutadiene and Cobaltcatalyzed high syndiotactic 1,2polybutadiene were studied.The result inducates:with the increase of content of syndiotactic polybutadiene in blend,its original mooney viscosity increases,and cold flow resistance improves.Cold flow disappears when content of syndiotactic polybutadiene is 4% process property is close to BR9000 when content of syndiotactic polybutadiene is 8%,tensile strength at 300% increaseing by 3 MPa,elongation s 460% and high comprehensive properties are obtained. |
