    • This invention relates to a novel polymerization initiator capable of introducing an active amino proton into a polymerization starting terminal without losing polymerization activity, and a novel modified conjugated diene polymer being excellent in the interaction with a filler and capable of improving a low heat buildup of a rubber composition, and more particularly to a polymerization initiator being a diamine compound in which one amino group is protected with a silylating agent and an active proton of the other amino group is replaced with an alkali metal or an alkaline earth metal, and a modified conjugated diene polymer which can be produced by using such a polymerization initiator and is a homopolymer of a conjugated diene compound or a copolymer of a conjugated diene compound and an aromatic vinyl compound and has a residue derived from a diamine compound at its polymerization starting terminal.
    • 本发明涉及一种能够在聚合起始末端引入活性氨基质子而不失去聚合活性的新型聚合引发剂,以及与填料相互作用优异且能够改善低聚合度的新型改性共轭二烯聚合物 更具体地说,涉及作为二胺化合物的聚合引发剂,其中一个氨基被甲硅烷基化剂保护,另一个氨基的活性质子被碱金属或碱土金属代替,并且改性共轭 二烯聚合物,其可以通过使用这种聚合引发剂制备,并且是共轭二烯化合物的均聚物或共轭二烯化合物和芳族乙烯基化合物的共聚物,并且在其聚合起始末端具有衍生自二胺化合物的残基。
