| titleOfInvention | Iron-based catalyst composition and method for producing syndiotactic 1,2-polybutadiene |
| abstract | PROBLEM TO BE SOLVED: To produce an iron-based catalyst composition and syndiotactic 1,2-polybutadiene. A catalyst comprising (a) an iron-containing compound, (b) an organomagnesium compound and (c) a dihydrocarbyl phosphite ester for polymerizing 1,3-butadiene into syndiotactic 1,2-polybutadiene. A composition is disclosed. By using the catalyst composition of this disclosure, the use of environmentally harmful components such as carbon disulfide and halogenated hydrocarbons is avoided. The melting temperature of the syndiotactic 1,2-polybutadiene can be varied from about 100 to about 190 ° C. by changing the composition ratio with the catalyst components. The ability to vary the melting temperature with a single catalyst composition is highly desirable. Syndiotactic 1,2-polybutadiene can be used as a plastic or additive for rubber compositions that can be crosslinked with conventional rubbers using conventional crosslinking agents.
