介绍金属配合物催化法合成超高分子量的、非结晶的聚烯烃的方法以及基本性质.讨论了催化剂用量、温度、时间等因素对聚合物特性粘度的影响.通过核磁共振等方法确定了所得到的聚合物的成分.经环道减阻评价系统测定了聚合物对柴油的减阻率.结果表明,在雷诺数Re为9000,柴油中添加量为10ppm时的减阻效果最大可达到40.5%.其减阻效果与美国同类产品基本相等.
The method and the basic properties of ultra-high molecular weight, non-crystalline polyolefins catalyzed by metal complexes were introduced.The effects of the amount of catalyst, temperature and time on the inherent viscosity of the polymers were discussed.It was confirmed by NMR and other methods that the obtained Of the polymer.The ring drag reduction system was used to determine the drag reduction ratio of the polymer to diesel.The results showed that the maximum drag reduction effect can reach 40.5% when the Reynolds number Re is 9000 and the diesel dosage is 10 ppm, The drag reduction effect is basically the same as that of similar products in the United States.
