Abstract

A thermoplastic, hydrogenated vinyl aromatic/conjugated diene block polymer composition, especially a hydrogenated styrene/butadiene triblock composition, functions well as a LED encapsulating material in that it provides one or more of optical clarity, thermal stability, ultraviolet light resistance, melt-processability and injection-moldability. The resulting LED resists deformation after setting or hardening under typical solder reflow conditions.
