Document Type and Number:
Japanese Patent JP7035056
Kind Code:
B2
Abstract:
The present disclosure relates to a multilayer pressure sensitive adhesive assembly comprising a polymeric foam layer and a first pressure sensitive adhesive layer adjacent to the polymeric foam layer, wherein the polymeric foam comprises a plurality of activated carbon particles distributed therein, and wherein the first pressure sensitive adhesive comprises:
a) a linear block copolymer having the formula M - (G) p , wherein M is a rubbery block comprising a polymerized olefin, a polymerized conjugated diene, a hydrogenated derivative of a polymerized conjugated diene, or any combinations thereof; wherein each G is a glassy block comprising a polymerized monovinyl aromatic monomer; and wherein p is 1 or 2;
b) at least one hydrocarbon tackifier;
c) a (meth)acrylate copolymer having a Tg higher than 25°C and a weight average molecular weight (Mw) comprised between 1000 and 100.000 Daltons, and comprising:
(i) (meth)acrylic acid ester monomer units having a Tg higher than 25°C when homopolymerized; and
(ii) optionally, monofunctional ethylenically unsaturated comonomer units;
d) optionally, a multi-arm block copolymer having the formula Sq-Z, wherein:
(i) S represents an arm of the multi-arm block copolymer and each arm independently has the formula G-N,
(ii) q represents the number of arms and is a whole number of at least 3, and
(iii) Z is the residue of a multifunctional coupling agent,
wherein each N is a rubbery block comprising a polymerized conjugated diene, a hydrogenated derivative of a polymerized conjugated diene, or combinations thereof; and
e) optionally, a diblock copolymer having the formula T - (G), wherein T is a rubbery block comprising a polymerized olefin, a polymerized conjugated diene, a hydrogenated derivative of a polymerized conjugated diene, or any combinations thereof. The present disclosure also relates to a method of manufacturing such a multilayer pressure sensitive adhesive assembly and uses thereof.
