摘　　要：合成了一种铁系间同1,2-聚丁二烯,对其进行了分子结构表征及基本性能评价,并与日本合成橡胶公司的RB系列产品进行了比较。结果表明,该催化体系的活性较高,且产物的收率也较高,其熔点可低于130℃,拉伸强度大于20 MPa。The iron-based high syndiotactic 1,2- polybutadiene was synthesized. The characterization of molecular structure and the evaluation of basic performance of the synthesized product were carried out and compared with RB series by Japan Synthetic Rubber Co. The results showed that the catalyst systern had a higher activity, the polymerization product had a higher yield and exhibited a lower melting point （lower than 130 ℃）and a great tensile strength（20 MPa）.
