Preparation of hydroxy-terminated conjugated diene polymers, particularly polybutadienes, by capping of organodilithium- and organopolylithium- terminated conjugated diene polymers or polybutadienes with lower alkylene oxide or epoxide capping agents in the presence of certain potentiating agents or catalysts exemplified particularly by small proportions of N,N,N.sup.1, N.sup.1 -tetramethylenediamine (TMEDA).
通过在某些促进剂或催化剂的存在下,使用较低的烷基氧化物或环氧化合物封端剂对有机二锂和有机聚锂终止的共轭二烯聚合物或聚丁二烯进行封端,特别是聚丁二烯的羟基终止的制备,例如通过少量N,N,N.sup.1,N.sup.1-四亚甲基二胺(TMEDA)进行示例化。
