  • Publication number: 20240141091
    Abstract: The disclosure relates to a styrenic block copolymer (SBC) having at least a triblock, and a diblock structure with a diblock content of up to 50 wt. %. The SBC is suitable for film applications requiring soft stretch properties even without adding oil, pressure sensitive adhesive applications, photocurable (photopolymerizable) printing plates, etc. Additional components can be added to the SBC, accordingly, forming the end-use (application) composition.

  • Patent number: 11692048
    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.
