Beschreibung
Zusammenfassung:	The invention provides a styrene-butadiene block copolymer and a preparation method thereof. The styrene-butadiene block copolymer has the structure shown as a formula (I), in which X1 and X2 are independently block copolymer segments of butadiene and styrene respectively, and R1 and R2 are independently C1-C6 linear-chain or branched-chain hydrocarbyl groups, C3-C12 cycloalkyl groups, C6-C15 aryl groups or C7-C12 aralkyl groups respectively. The styrene-butadiene block copolymer provided by the invention has relatively excellent mechanical properties. 本发明提供了种丁苯嵌段共聚物及其制备方法。所述丁苯嵌段共聚物具有式(I)所示的结构，在式(I)中，X和X各自独立地为丁二烯和苯乙烯的嵌段共聚链段，R和R各自独立地为C-C的直链或支链烃基、C-C的环烷基、C-C的芳基或C-C的芳烷基。本发明提供的丁苯嵌段共聚物具有较为优异的力学性能。
