VECTOR 4113A 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 not formulated with the antioxidant TNPP (tris(nonylphenyl) phosphite).
It is a soft SIS/SI block copolymer blend. It is softer than VECTOR 4111A pure triblock copolymer due to the presence of ~18% SI diblock. It is well suited for use in formulating adhesives and in photopolymer plate applications.
