description | The multilayer pressure sensitive adhesive assembly includes a polymeric foam layer and a first pressure sensitive adhesive layer. The polymeric foam includes a plurality of activated carbon particles. The first pressure sensitive adhesive layer includes a multi-arm block copolymer in an amount greater than 20 percent by weight, based on the weight of the first pressure sensitive adhesive layer, and at least one hydrocarbon tackifier. The multi-arm block copolymer has formula Qn-Y, in which Q represents an arm of the multi-arm block copolymer, each arm independently having the formula G-R, n represents the number of arms and is at least 3, and Y is the residue of a multifunctional coupling agent. Each R is independently a rubbery block including a polymerized conjugated diene, a hydrogenated derivative of a polymerized conjugated diene, or combinations thereof, and each G is a glassy block including a polymerized monovinyl aromatic monomer. |
