Abstract
Abstract An adhesive composition comprising a) a tackifying resin, b) a styrene-isoprene-styrene block copolymer or a styrene-isoprene block copolymer with styrene blocks as the end blocks and having at least one internal block of an acrylic monomer, and c) a block copolymer of at least one vinyl aromatic hydrocarbon, at least one conjugated diolefin and at least one acrylic monomer, such as an alkyl methacrylate, which is on the end of the copolymer and is attached to a conjugated diolefin block.

Claim 1
Independent Claim
133 words
An adhesive composition a) comprising a tackifying resin, b) a styrene-isoprene block copolymer with styrene blocks as the end blocks and having at least one internal block of an acrylic monomer, and c) a block copolymer of at least one vinyl aromatic hydrocarbon, at least one conjugated diolefin and at least one acrylic monomer which is on the end of the copolymer and is attached to a conjugated diene block and has the structure ##STR3## wherein R 1 is selected from the group consisting of hydrogen, phenyl and alkyl radicals which are linear or branched and contain from 1 to 10 carbon atoms, and R 2 is H or a cyclic or non-cyclic alkyl radical which contains from 1 to 14 carbon atoms and may contain a tertiary amine or an ether linkage.
Claim 2
Dependent Claim
