## Abstract The activity of an aluminum complex/polysilanol polymerization catalyst was examined in order to confirm the dependence of catalytic activation on silanol chain length. Tris (acetylacetonato)βaluminum/silanol increased when silanols with an intramolecular hydrogen bond such as the trime
The polymerization of butadiene in toluene using Co(acac)3-(i-Bu)3Al-H~O catalyst system was studied. Presented are the effects of the addition order, aging time, and composition of catalysts on rates, polymer microstructure, and molecular weights. The polymerization was found to be initiated by the
## Abstract The catalytic activity of an aluminum complex/silanol system was found to vary with the aluminum ligand as follows: Ξ²βdiketonate < Ξ²βketoester anion < orthoβcarbonylphenolate. Aluminum complexes with electron donating groups conjugated with a carbonyl group had higher catalytic activity
