    • This is a process for the partial hydrogenation of conjugated diene polymers which comprises polymerizing at least one conjugated diene using an organo alkali metal polymerization initiator in a suitable solvent thereby creating a living polymer comprising (1) ethylenic unsaturation between backbone carbons wherein at least one of the doubly bound backbone carbons is substituted and (2) ethylenic unsaturation which is not between doubly bound backbone carbons wherein at least one is substituted, terminating the polymerization, and effecting selective hydrogenation of the ethylenic unsaturation in the conjugated diene units of the terminated polymer which is not between doubly bound backbone carbons wherein at least one is substituted, by contacting the polymer with hydrogen in the presence of no more than 0.02 mmol of catalyst per gram of polymer of a bis(cyclopentadienyl)titanium catalyst.
    • 这是共轭二烯聚合物的部分氢化的方法,其包括使用有机碱金属聚合引发剂在合适的溶剂中聚合至少一种共轭二烯,从而产生活性聚合物,其包括(1)骨架碳之间的烯属不饱和键,其中至少一个 双重键合的骨架碳被取代,和(2)不在双键结合的骨架碳之间的烯键式不饱和键,其中至少一个被取代,终止聚合,并且对端基聚合物的共轭二烯单元中的烯属不饱和键进行选择性氢化, 在不超过0.02mmol催化剂存在下,每克双(环戊二烯基)钛催化剂的聚合物存在下,通过使聚合物与氢接触,不在双键结合的骨架碳之间。
