Appeal No. 98-3225 2
Application No. 08/204,162
THE INVENTION
The invention is directed to a viscoelastic damping foam having an adhesive surface.
The surface is prepared from a stoichiometric reaction of a polyisocyanate with a mixture
of polyols. One polyol is based on polyethylene oxide and the other on polypropylene
oxide. Additional features of the claimed subject matter are set forth in the following
illustrative claim.
THE CLAIMS
Claims 6 is illustrative of appellants’ invention and is reproduced below.
6. A viscoelastic damping foam having an adhesive surface comprising a
stoichiometric reaction product of a polyisocyanate and a polyol reactant, said polyol
reactant consisting essentially of a first polyether polyol based on propylene oxide and a
second polyether polyol based on ethylene oxide, wherein said first and said second
polyether polyols have hydroxyl numbers no greater than 100, and wherein said first
polyether polyol and said second polyether polyol are present in a weight ratio of from
5:1 to 1:5.
THE REJECTION
Claims 6 through 11 stand rejected under 35 U.S.C. § 112, first paragraph, as
containing subject matter which was not described in the specification in such a way as to
reasonably convey to one skilled in the relevant art that the inventor(s), at the time the
