摘要： The present disclosure relates to a pressure sensitive adhesive comprising:
a) a multi-arm block copolymer of 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 M w comprised between 10.000 and 100.000 g/mol;
c) at least one hydrocarbon tackifier which is primarily compatible with the rubbery blocks;
d) a glassy block compatible aromatic resin having a softening point value (RBSP) of at least 150°C, when measured by the ring and ball test method described in the experimental section; and
e) optionally, a linear block copolymer of 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.
The present disclosure also relates to a method of manufacturing such a pressure sensitive adhesive and uses thereof.
