Appeal No. 1999-1158
Application No. 08/687,427
certain types of monomers. This appealed subject matter is
adequately illustrated by independent claim 1 and dependent
claim 8 which read as follows:
1. A method, comprising adhering a floor covering to a
floor with a floor adhesive comprising an aqueous composition,
free of organic solvents, plasticizers, and additional
tackifiers, containing water and
20-99% by weight of a polymer having a glass transition
temperature below -25EC, the polymer being composed of (1) from
60 to 100% by weight of C C alkyl(meth)acrylates, vinyl esters
1- 20-
of carboxylic acids of up to 20 carbon atoms, vinyl aromatics of
up to 20 carbon atoms, ethylenically unsaturated nitriles, vinyl
halides, non-aromatic hydrocarbons having at least two
conjugated double bonds or mixtures of these monomers, and
1-80% by weight of a filler,
the percentages by weight being based on the sum of the
components of the aqueous composition, with the exception of
water, the floor adhesive being applied to one side of the floor
covering.
8. The method of claim 1, wherein the polymer does not
contain ethylene monomers.
The references relied upon by the examiner as evidence of
non-
obviousness are:
