Application No. 08/890,134
APPENDIX
Claim 1
1. An adhesive composition, comprising:
A) a base composition, comprising
(i) 15-35 wt% of an unhydrogenated elastomeric block
copolymer having a polymerized conjugated diene
midblock portion and at least two polymerized
monovinyl arene endblock portions, each of said
endblock portions having a molecular weight within
the range of 13,000 to 30,000, wherein said
endblock portions are present at a total
concentration within the range of 20 to 24 %wt
based upon the total weight of said unhydrogenated
elastomeric block copolymer; and
(ii) 85-65 wt% based on the total weight of (i) and
(ii) of tackifying components comprising a
midblock compatible resin and oil, said midblock
compatible resin and said oil being present in a
weight ratio within the range of 1.5:1 to 3.5:1
midblock compatible resin:oil and said midblock
compatible resin and said unhydrogenated
elastomeric block copolymer being present in a
weight ratio of at least 120:100 midblock
compatible resin:unhydrogenated elastomeric block
copolymer; and
B) a stabilizer, said stabilizer being present in an
amount within the range of 0.01 to 5 wt% based on the
weight of said base composition.
