Title:
Moが基になった触媒組成物を用いて共役ジエン重合体の性質を調節する方法
Document Type and Number:
Japanese Patent JP4970691
Kind Code:
B2
Abstract:
A catalyst composition that is the combination of or the reaction product of ingredients including (a) a molybdenum-containing compound, (b) a hydrogen phosphite, and (c) a blend of two or more sterically distinct organoaluminum compounds. This catalyst composition is particularly useful for polymerizing conjugated dienes. When this catalyst composition is used to polymerize 1,3-butadiene into syndiotactic 1,2-polybutadiene, the ratio of the organoaluminum compounds can be adjusted to vary the melting temperature and molecular weight of the polymer product.
