【発明の名称】水素化した共役ジエンポリマーを製造する方法
Document Type and Number:
Japanese Patent JP2002503275
Kind Code:
A
Abstract:
A process for making hydrogenated polymers is presenting. Polymerization is initiated with a lithium initiator and one or more unsaturated monomers are polymerized to a polymer cement. The polymerization process is terminated and dry carbon dioxide is introduced to the polymer cement to make a CO2-treated polymer cement. The CO2-treated polymer cement is hydrogenated in the presence of a Ni/Al catalyst.
