than about 5 mole percent, based on the amount of monoether, of polyoxyalkylene
diols. The appealed subject matter also relates to a method of using such a
composition. This appealed subject matter is adequately illustrated by independent
claim 13 which reads as follows:
13. A composition which comprises:
(a) an oleophilic polyoxyalkylene monoether of the structure:
Z—(A)n—OH
wherein A is an oxyalkylene group, Z is a hydrocarbyl
residue selected from the group consisting of C4-C60
alkyl, aryl, and aralkyl, and n, which is the average
number of oxyalkylene groups, is within the range of
about 2 to about 500; and
(b) less than about 6 mole percent, based on the amount
of monoether, of alkoxylated unsaturates.
The references set forth below are relied upon by the examiner as evidence of
obviousness:
Manary 3,615,295 Oct. 26, 1971
Polss 3,901,665 Aug. 26, 1975
Under 35 USC § 103(a), claims 1-3, 5-20, 22, 24, 26, 30 and 31 are rejected as
being unpatentable over Manary, and claims 1, 2, 4-18, 21, 23, 25, 27, 30 and 31 are
rejected as being unpatentable over Polss.
