| In this article, the source and development of SEBS is analyzed, the technology advancements, trends and the development situations at home are summarized, and the characteristics of the microstructure of SEBS and the factors affecting the control of its microstructure is investigated. The existing quality problems of SEBS are theoretically analyzed, and the reasons affecting its mechanical properties have been found. The methods for representing the microstructure of SEBS have been established. The effects of different structure regulators on polymerization reaction, microstructure and macro properties of SEBS basis have been studied. And regulator A/regulator E has been identified as the proper structure regulator for SEBS polymerization to control its 1,2-structure within the proper range. The mechanical properties of SEBS product with microstructure having been optimized are equivalent to those of foreign similar products. |
