Application No. 08/432,560
find that another unnamed emulsifier resulting from the
emulsion polymerization of the polyol is present in the
composition of Hombach.
The examiner relies upon Weissgerber for its disclosure
of the claimed emulsifier used in the polymerization of
olefinically unsaturated monomers containing hydroxy groups.
We find that Weissgerber discloses the emulsion polymerization
of ethylenically unsaturated polyols using appellants’
preferred emulsifier. See Comparative Example A and Examples
1 and 2. We find that the addition of 18 grams of
concentrated ammonium hydroxide to sodium nonylphenyl
polyglycolether sulfate as disclosed in the above examples
results in the formation of the emulsifier of the claimed
subject matter. We conclude that it would have been obvious
to the person having ordinary skill in the art to prepare
Hombach’s polyol using the emulsifier of Weissgerber for its
ordinary intended purpose.
As for appellants’ argument that both Hombach and
Weissgerber are directed to adhesive compositions as opposed
to appellants’ coating composition, we find that both
references disclose the utilization of their respective
