Appeal No. 2000-0026
Application No. 08/942,054
find absolutely none of the requisite motivation to add any
amount of solvent to the structural adhesive composition of
Briggs, let alone appellant's at least about 10% of organic
solvent. The methacrylate ester monomers, preferably methyl
methacrylate, of Briggs' structural adhesive compositions are
specifically taught to be the solvent in which the elastomers
are dissolved, to which solution the core-shell polymers are
added to form, ultimately, a smooth paste. Manifestly, since
Briggs does not need an additional organic solvent, the
reference provides no teaching or suggestion of modifying the
disclosed composition by adding at least about 10% by weight
of an organic solvent. On the other hand, there is no
teaching or suggestion of modifying the solvent-containing
pipe adhesive of Patel by incorporating the presently claimed
polymeric components.
Accordingly, based on the foregoing, we are constrained
to reverse the examiner's rejection.
