Title:
A bulk polymerization method for manufacturing the poly Diene
Document Type and Number:
Japanese Patent JP5955211
Kind Code:
B2
Abstract:
A method of producing cis-1,4-polydienes, the method comprising the step of contacting conjugated diene monomer with a lanthanide-based catalyst system in the presence of less than 20% by weight of organic solvent based on the total weight of monomer, organic solvent, and resulting polymer, where the lanthanide-based catalyst system is the combination of or reaction product of (a) a lanthanide compound, (b) an organoaluminum hydride, (c) a trihydrocarbylaluminum, and (d) a halogen-containing compound.
