Appeal No. 95-1077
Application 07/965,647
sulfide polymers disclosed in Hoover have melt flow values
preferably ranging from about 5 to about 700 g/10 min., and
more preferably, ranging from about 10 to about 500 g/10 min.
(col. 10, lines 6-11). Compare appellants’ specification p.4,
lines 11-14 (“The poly(arylene sulfide) polymers prepared
according to the invention process generally exhibit melt flow
values (rates) in the range of 2-700 g/10 min.”). However,
relying on Examples I and II disclosed in Hoover, appellants
argue that Hoover does not disclose “essentially linear”
arylene sulfide polymers having a melt flow rate within the
range recited in claim 12.
The method disclosed in Example II, illustrating the
method outlined above, is said to produce an “essentially
linear” arylene sulfide polymer which exhibits a melt flow
rate of 401 g/10 minutes. In comparison, the method disclosed
in Hoover Example I, wherein the monomer source (b) comprises
a mixture
of at least one dihaloaromatic compound and at least one
polyhaloaromatic compound, is said to produce a “branched”
