SBS，SIS，SEBS，SEPS区别
以下是主要TPS苯乙烯弹性体：
The following symbols are used for the TPS group:
TPS-SBS: Block copolymer of styrene and butadiene
TPS-SBS 苯乙烯-丁二烯-苯乙烯嵌段共聚物
TPS-SEBS: Polystyrene-poly(ethylene-butylene)-polystyrene
TPS-SEBS：
TPS-SEPSolystyrene-poly(ethylene-propylene)-polystyrene
TPS-SIS: Block copolymer of styrene and isoprene.
Note: TPS-SEBS is a block copolymer of styrene andbutadiene in which the soft block comprises a mixture of hydrogenatedcis-1,4-polybutadiene, and 1,2-polybutadiene units.
TPS-SEPS is ablock copolymer of styrene and isoprene in which the polyisoprene block hasbeen hydrogenated.
SIS是苯乙烯和共轭二烯烃组成的嵌段共聚物，中部的软段由聚异戊二烯橡胶段组成，其中不饱和共轭二烯键的化学性质比较活泼，性能不稳定，因此限制了它们在户外环境中的广泛使用。若采用选
