  • Linear SIS triblock copolymer.
  • Contains <1% diblock copolymer.
  • Medium styrene, medium modulus.

VECTOR 4211A and VECTOR 4211N styrenic block copolymers are linear triblock copolymers with narrow molecular weight distributions. They have a higher styrene content and higher modulus than VECTOR 4111A SIS, making them well-suited for use in elastomer compounds, polymer modification applications and pressure sensitive adhesive applications requiring high cohesion.

  • VECTOR 4211A SIS is offered as a dense pellet supplied from the United States.
  • VECTOR 4211N SIS is offered as a porous pellet supplied from China.
