Appeal No. 2001-0742
Application 09/128,912
Appellants urge that despite the fact that the
polymeric compositions of the references may be similar to
appellants’ composition, the claimed films are not the same as
those of the cited references, because “the composition of a
latex polymer clearly does not solely dictate final physical end
properties of crosslinked films made therefrom.” Appeal Brief,
page 4. In particular, appellants note that the extent of latex
film crosslinking is due to a number of factors such as gel
content, swell area, etc. which are dependent upon processing
temperature, extent of conversion, rate of reaction, polymer
concentration, catalyst concentration, etc. Id. Appellants
further note that film performance properties are influenced
during the inherent stage of polymer formation as well as during
post polymerization crosslinking, which is influenced by factors
such as cure additives. Id. In support of their position,
appellants reference three separate articles which were submitted
with appellants’ amendment received December 9, 1999, Paper No.
9. Appellants rely on these articles as proof that the
properties of latex polymers are determined by variables other
than composition alone.
