铁系间同1,2-聚丁二烯的合成与性能 张林 宋玉萍 谭振明 李洪波 毕吉福 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. Synthesis and properties of syndiotactic 1,2-polybutadiene with iron catalyst Zhang Lin(Research Institute of Dushanzi Petrochemical Company,PetroChina,Dushanzi 833600,China) Song Yuping(Research Institute of Dushanzi Petrochemical Company,PetroChina,Dushanzi 833600,China) Tan Zhenming(Research Institute of Dushanzi Petrochemical Company,PetroChina,Dushanzi 833600,China) Li Hongbo(Research Institute of Dushanzi Petrochemical Company,PetroChina,Dushanzi 833600,China) Bi Jifu(Changchun Institute of Applied Chemistry,Chinese Academy of Sciences,Changchun 130022,China) Abstract: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 system 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). |
