Latest Patents
Soga's latest patents include a process for producing olefin living polymers. This innovative process allows for the preparation of olefinic living polymers with a molecular weight distribution (Mw/Mn) ranging from 1 to 1.3. The method involves polymerizing an olefinic monomer with 2 to 20 carbon atoms at low temperatures using a specific catalyst. This catalyst comprises a hafnium or zirconium-containing compound, a triphenyl boron compound, and optionally, a mono-, di-, or trialkylaluminum compound. Additionally, when a titanium-containing compound is used, the polymerization temperature can be increased.
Another notable patent focuses on butadiene polymers and the process for producing conjugated diene polymers. This invention describes a butadiene polymer with a cis bond unit content of at least 50% and a number average molecular weight (Mn) ranging from 1,000 to 10,000,000. The polymers are obtained through the polymerization of a conjugated diene monomer in the presence of a catalyst that includes a transition metal compound and an organoaluminum-oxy compound.
