| Linear SIS triblock copolymer. Contains <1% diblock copolymer. Low styrene, low modulus. VECTOR 4111A and VECTOR 4111N styrenic block copolymers are linear triblock copolymers with narrow molecular weight distributions. They are the softest pure triblock copolymers offered and show outstanding melt processability and elasticity, making them well-suited for use in elastomer compounds and polymer modification applications. The pure triblock also makes them well-suited for use in high shear, pressure sensitive adhesive applications. VECTOR 4111A SIS is offered as a dense pellet supplied from the United States. VECTOR 4111N SIS is offered as a porous pellet supplied from China.&& |
