within the 3 to 8 range, and 2) a carboxylic acid component
including, in an amount which should be at least about 50 wt%,
an aromatic or a cycloaliphatic carboxylic acid, and
optionally including acyclic carboxylic acids and anhydrides
which can be maleic acid, maleic anhydride or fumaric acid
(col. 2, lines 16-24 and 40-49; col. 2, line 60 - col. 3, line
3). The functionality can be controlled by a including in the
composition a monoalcohol or a monofunctional acid (col. 2,
lines 57-59; col. 3, lines 4-6 and 29-33). The teaching that
“[b]y varying the amounts and functionalities of the
individual components, polyester polyols with virtually any
theoretical average functionality may be obtained” (col. 3,
lines 33-36) would have fairly suggested, to one of ordinary
skill in the art, including in the composition any amount of
monoalcohol or monofunctional acid needed to obtain the
desired functionality, such as amounts of at least 10 mole%.
Nodelman’s disclosure of polyol A, wherein the monofunctional
acid (2-ethylhexanoic acid) is present in an amount of 11.8
mole% of the acid and anhydride components, further would have
fairly suggested, to one of ordinary skill in the art,
