Color prevention in titanium catalyzed hydrogenated diene polymers |
摘要 |
The present invention is an improvement upon a process for hydrogenating a diene polymer by contacting the polymer in the presence of hydrogen with a titanium hydrogenation catalyst. The improvement comprises preventing discoloration of the hydrogenated polymer by treating it with water, a peroxide or alcohol in the absence of oxygen and adding a non-phenolic antioxidant to the polymer.
