Appeal No. 1996-1284
Application No. 08/084,685
We note that appellant bases no argument upon objective
evidence of nonobviousness which demonstrates that the claimed
diamine produces unexpected results in the random
copolymerization process vis-�-vis the tertiary amines
disclosed by GB '490. Moreover, appellant acknowledges that
Prudence, U.S. Patent No. 4,230,841, evidences that it was
known in the art to use the presently claimed tetramethyl-
ethylenediamine as a modifier in the copolymerization of
butadiene with a vinyl aromatic compound, specifically, a
divinyl aromatic compound (see page 3 of Reply Brief, last
paragraph).
In conclusion, based on the foregoing, the examiner's
decision rejecting the appealed claims is affirmed.
No time period for taking any subsequent action in
connection with this appeal may be extended under
37 CFR � 1.136(a).
AFFIRMED
