摘要： 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) a multi-arm block copolymer having the formula Q n -Y, wherein:
(i) Q represents an arm of the multi-arm block copolymer and each arm independently has the formula G-R,
(ii) n represents the number of arms and is a whole number of at least 3, and
(iii) Y is the residue of a multifunctional coupling agent,
wherein each R is a rubbery block comprising a polymerized conjugated diene, a hydrogenated derivative of a polymerized conjugated diene, or combinations thereof; and each G is a glassy block comprising a polymerized monovinyl aromatic monomer;
b) a polymeric plasticizer having a weight average molecular weight Mw of at least 10.000 g/mol;
c) at least one hydrocarbon tackifier, wherein the hydrocarbon tackifier(s) have a Volatile Organic Compound (VOC) value of less than 1000 ppm, when measured by thermogravimetric analysis according to the weight loss test methods described in the experimental section; and
d) optionally, a linear block copolymer having the formula L - (G) m , wherein L is a rubbery block comprising a polymerized olefin, a polymerized conjugated diene, a hydrogenated derivative of a polymerized conjugated diene, or any combinations thereof; and wherein m is 1 or 2;
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; and wherein p is 1 or 2;
b) at least one second 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.
