Abstract
A gel composition is herein disclosed. According to one embodiment, the composition comprises a (i) a styrenic block copolymer, (ii) an oil; and (iii) optional additives; wherein the styrenic block copolymer has a structure ABi or iAB, wherein A is a monoalkenyl arene block, B is a conjugated diene block, and i is an isoprene attachment. The isoprene attachment i is substantially unsaturated and the conjugated diene block B is substantially saturated. The gel composition before curing exhibits thixotropic behavior, with a viscosity ranging from about 5000 mPa·s to about 30000 mPa·s. at 25° C. and a shear rate of 20 s−1.
