New SBC Polymers and Applications

摘要

Styrenic Block Copolymers (SBCs) are a very versatile class of polymers. Also classified as TPE-S in the field of thermoplastic elastomers they are used to upgrade the performance of other polymers in a broad range of different application areas. The precise control of anionic polymerization and the compounding formulation latitude enables this polymer system and resulting compounds to deliver tailor-made solutions for a wide range of application requirements. New Kraton polymer families and their compounds offer an economical alternative to PVC applications in automotive, wire and cable, and medical applications. NEXARTM polymers are an example where tailored polymer design and post-polymerization functionalization lead to a totally new class of SBC’s – selectively sulfonated SBCs. The new pentablock-copolymers show unique properties such as extremely high water transmission rates, where these SBC’s can be used in totally new application areas including membrane technologies.
