| 摘 要： | <正> 目前合成SBS的一般方法是以单锂烷基化合物,按二步法、三步法或偶合法进行,更简便的方法是用双锂引发剂一步法合成SBS。该方法基于苯乙烯、丁二烯彼此间竞聚率差别很大,将两种单体混在一起亦可进行嵌段共聚,与三步法或偶合法的差异是:在聚丁二烯嵌段两端存在着丁苯无规成份,文献称之为“tapered”SBS共聚物。

| Abstract: | Dilithium initiator (LM-T) based on lithium-Aromatic complex was studied. Using LM-T as initiator and non-palar hydrocarbon as polymerization solvent, styrene-buta-diene-styrene triblock copolymer (SBS) was syntherized by one-step feed method. The characterization of SBS obtained by this initiator was curried out by means of IE, NME, GPC and mechanical properties determination. Comparison was made with sample prepared with monolithium initiator by twostep feed methed. |
