Title: FUSIBLE OIL GEL COMPOSITIONS AND METHODS OF MAKING AND USING SAME
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 comprises: a diblock polymer having a monoalkenyl arene block, designated A, a conjugated diene block, designated B, an isoprene attachment, designated i, and wherein the styrenic block copolymer can have structure ABi or iAB; the isoprene attachment i is substantially unsaturated and the conjugated diene block B is substantially saturated. The gel composition before curing exhibits thixotropic behavior, and the gel composition after curing is either elastic solid or has a viscosity at 25 °C at a shear rate of 20 s-1 of at least 30000 mPa.s.
