发明名称 ELASTOMERIC COMPOSITIONS THAT RESIST FORCE LOSS AND DISINTEGRATION
摘要 Embodiments of the present disclosure may provide various properties of slow recovery polymers, films, and laminates that in combination with an hydrogenated block copolymer provide for (1) an order-disorder transition temperature of greater than about 135° C., (2) a hard phase glass transition temperature of greater than about 60° C., (3) a combination of one or more hard block associating ingredients that maintain or increase the glass transition temperature of at least one equivalent hard block polymer of the hydrogenated block copolymer, (4) a force retention factor of greater than about 2, (5) aromatic substitution of either or both the soft block and the hard block, (6) hard blocks with a solubility parameter of greater than about 9.1 (cal/cm3)1/2, and (7) compositions that remain extendable to at least 50% engineering strain after exposure to isopropyl palmitate for 30 hours at room temperature.
