Abstract
Provided herein is a composition containing a hydrogenated blend of a semi-crystalline, selectively hydrogenated block copolymer, a selectively diblock copolymers lacking semi-crystalline blocks, and a low polarity fluid for cable filling applications. The block copolymer comprises blocks of semi-crystalline hydrogenated polybutadiene, blocks of poly(mono alkenyl arenes), and blocks of hydrogenated, non-crystalline conjugated dienes. The diblock copolymer comprises blocks of poly(mono alkenyl arenes) and blocks of non-crystalline poly(conjugated diene(s)). The compositions can be converted to non-flowable gels and find application as fillers for cables such as fiber optic cables.
