  The instant invention teaches a method for forming a syndiotactic 1,2-polybutadiene product having a higher syndiotacticity and a higher melting temperature than syndiotactic 1,2-polybutadiene produced using chromium catalysts known in the prior art. The method includes polymerizing 1,3-butadiene in solution with a solvent, in the presence of catalytically effective amounts of (a) an organomagnesium compound; (b) a chromium compound; and, (c) a cyclic hydrogen phosphite.

  A catalyst composition comprising (a) an iron-containing compound, (b) a cyclic hydrogen phosphite, and (c) an organoaluminum compound 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 125 to about 175 °C by variations in the catalyst components and the component ratios. The ability to vary the melting temperature over such a broad range 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.

  本发明公开了一种由(a)含铁化合物、(b)环状亚磷酸氢盐和(c)有机铝化合物组成的催化剂组合物，用于将 1,3-丁二烯聚合成对位 1,2-聚丁二烯。使用本公开的催化剂组合物可以避免使用二硫化碳和卤代溶剂等有害环境的成分。通过改变催化剂组分和组分比例，辛二聚丁二烯的熔化温度可在约 125 ℃ 至约 175 ℃ 之间变化。使用单一催化剂成分就能在如此大的范围内改变熔化温度，这是非常理想的。辛二聚丁二烯可用作塑料或橡胶组合物的添加剂，其中辛二聚丁二烯可使用常规交联剂与常规橡胶交联。
