Appeal No. 1996-1735
Application No. 08/184,526
The subject matter on appeal is directed to a latent
activatable composite and a composition formed from the same.
According to appellants, “claims [1-15] do not stand or fall
together.” See Brief, page 3. However, appellants have not
supplied any substantive arguments for the separate
patentability of claims 1, 2 and 5 through 15 in accordance
with 37 CFR
§ 1.192(c)(7)(1995). See Brief, pages 8-11. Therefore, for
purposes of this appeal, we will limit our discussion to
claims 1, 3 and 4, which are reproduced below:
1. A latent activatable composite comprising a base
system chosen from the group consisting of epoxies,
polysulfides and cyanoacrylates and one or more amine-
terminated polyamide curatives dispersed in the base system
wherein said composite cures upon activation to form a
composition by the reaction of the base system and the
polyamide curative or curatives, wherein the ratio of amine
group equivalents to acid group equivalents comprising the
polyamide curative or curatives is from about
1.05 : 1.00 to about 1.95 : 1.00 equivalents NH :COOH wherein
X
x is 1 or 2.
3. The latent activatable composite of claim 2 wherein
at least one polyamine is selected from 2-methylpentamethylene
diamine, hexamethylene diamine, diethylene triamine,
piperazine and mixtures thereof and wherein at least one
polycarboxylic acid is selected from sebacic acid, azelaic
acid, dodecanedioic acid, dimer acid, trimer acid and mixtures
thereof.
