Appeal No. 95-1077
Application 07/965,647
Rejection of claim 12
Hoover discloses high molecular weight arylene sulfide
polymers and two methods of preparing these polymers. The
first method disclosed in Hoover comprises contacting, in a
polymeri-zation mixture, reactants comprising (col. 5, lines
40-46):
(a) an alkali metal sulfide (compare col. 6, lines 16-20
with appellants’ specification p.3, lines 10-14);
(b) a monomer source which comprises at least one
dihaloaromatic compound (compare col. 7, line 38-col. 8, line
2 with appellants’ specification p.2, line 11-p.3, line 3);
(c) an organic amide (compare col. 6, lines 56-68 with
appellants’ specification p.3, lines 20-29);
(d) an alkali metal carboxylate (compare col. 7, lines 1-
29 with appellants’ specification, p.3, lines 30-34); and
(e) water (compare col. 3, line 68-col. 4, line 3 (“the
total amount of water present during the polymerization
process ranges from about 1.02 mole to about 2.1 moles for
each mole of sulfur present in the resulting resin”) with
appellants’ claim 12 (“water in an amount less than about 1.75
moles water per mole of sulfur”)).
Thus, Hoover and appellants contact substantially the same
reactants in a polymerization mixture to produce arylene
sulfide polymers.
As correctly pointed out by the examiner, the arylene
