Styrene → Benzene, ethenyl-, polymer with 1,3-butadiene

Participants

Reaction Steps

The hydrogeneated styrene triblock copolymer elastomers SEBS and SEPS can be prepared by a general anionic living polymerization method. One example of the anionic living polymerization method is to produce a triblock copolymer by successive polymerization of styrene, butadiene and styrene and then hydrogenate the triblock copolymer. Another example of the anionic living polymerization method is to produce a styrene-butadiene diblock copolymer, treat the diblock copolymer with a coupling agent to form a triblock copolymer, and then, hydrogenate the triblock copolymer. The hydrogeneated styrene triblock copolymer elastomer SEPS can be prepared by the same method as above using isoprene instead of butadiene.
