This is an appeal from the final rejection of claims 1-6,
all the claims in the present application. Claim 1 is
illustrative:
1. A high service temperature sealant composition having
a shear adhesion failure temperature of greater than 60EC and
a slump temperature of greater than 70EC comprising:
(a) 100 parts of a functionalized selectively
hydrogenated block copolymer of a vinyl aromatic hydrocarbon
and a conjugated diene to which has been grafted at least 4%
by weight of an acid compound or an anhydride, salt, ester,
imide, amide, ether, nitrile, acid chloride, thiol, thioacid,
glycidyl, cyano, hydroxy, or glycol derivative thereof wherein
substantially all of the acid compound or its derivative is
grafted to the block copolymer in the conjugated dienes
blocks,
(b) 10 to 400 parts of a tackifying resin,
(c) 0 to 150 parts of an endblock reinforcing resin, and
(d) 0 to 150 parts of a plasticizing oil.
In the rejection of the appealed claims, the examiner
relies upon the following references:
