VECTOR 4114 is a blend of linear, pure styrene-isoprene-styrene triblock and pure styrene-isoprene diblock copolymers. The individual components are produced via proprietary sequential anionic polymerization technology from Dexco Polymers LP, a Dow/ExxonMobil Venture. It is formulated with the antioxidant TNPP (tris(nonylphenyl) phosphite).
It is the softest SIS/SI block copolymer blend due to the presence of ~42% SI diblock. It is designed for use in the modification of the modulus properties of olefinic resins and in formulating adhesives.
