Modification progress of styrene-butadiene-styrene block copolymer and their application in adhesives

The structure and properties of styrene-butadiene-styrene (SBS) block copolymer were introduced. The modification progress of SBS on hydrogenation, sulfonation, epoxidation and grafting was reviewed detailedly, and their application situation in adhesives was also presented. It was also pointed out that SBS-based adhesives should be given more attention to the development for high performance and function combined with actual production, and the production process should be optimized.
