Abstract
The present invention comprises an uncrosslinked composition of a styrenic block copolymer and PMS-I/B-PMS (paramethylstyrene-isoprene/butadiene-paramethylestyrene) block copolymer, optionally with one or more antioxidants and a carbon radical scavenger. The mid-block IB is a random mixture of isoprene and butadiene. Further, a process is disclosed for making the uncrosslinked composition. The present invention also includes an uncrosslinked composition of homo polystyrene, and PMS-I/B-PMS block copolymer, optionally with one or more antioxidants and a carbon radical scavenger. The present invention also comprises a crosslinked polyolefin-free composition of PMS-I/B-PMS block copolymer, optionally with a styrenic block copolymer and one or more antioxidants, a carbon radical scavenger, and free radical initiator. The present invention also includes an article incorporating an uncrosslinked composition of a styrenic block copolymer and homo polystyrene, and PMS-I/B-PMS block copolymer, optionally with one or more antioxidants and a carbon radical scavenger.
