    • PROBLEM TO BE SOLVED: To provide an iron-based catalyst composition and to provide a process for producing syndiotactic 1,2-polybutadiene.SOLUTION: The catalyst composition comprises (a) an iron-containing compound, (b) an organomagnesium compound and (c) a dihydrocarbyl hydrogen phosphite is disclosed for polymerizing 1,3-butadiene into syndiotactic 1,2-polybutadiene. The use of the catalyst composition of this disclosure avoids the use of environmentally detrimental components such as carbon disulfide and halogenated solvents. The melting temperature of the syndiotactic 1,2-polybutadiene can be varied from about 100 to about 190°C by variations in the catalyst components and the component ratios. The ability to vary the melting temperature with a single catalyst composition is very desirable. The syndiotactic 1,2-polybutadiene can be used as a plastic or as an additive for rubber compositions, wherein it can crosslink with conventional rubbers using conventional crosslinking agents.
    • 待解决的问题:提供铁基催化剂组合物并提供间规1,2-聚丁二烯的制备方法。 解决方案:催化剂组合物包含(a)含铁化合物,(b)有机镁化合物和(c)二烯烃亚磷酸氢盐,用于将1,3-丁二烯聚合成间规1,2-聚丁二烯。 使用本公开的催化剂组合物避免使用环境有害组分如二硫化碳和卤化溶剂。 间同立构1,2-聚丁二烯的熔融温度可以通过催化剂组分和组分比的变化从约100至约190℃变化。 用单一催化剂组合物改变熔融温度的能力是非常理想的。 间规1,2-聚丁二烯可以用作塑料或作为橡胶组合物的添加剂,其中它可以使用常规的交联剂与常规的橡胶交联。 版权所有(C)2013,JPO&INPIT
