acid component and a monomeric polyol component, wherein at least one of
the monomeric polycarboxylic acid component and the monomeric polyol
component has an average functionality of at least 2.2 and wherein said
adduct has residual carboxylic and hydroxyl groups and an acid number of
100 or above.
11. A method for binding together a loosely associated mat of glass
fibers comprising (1) contacting said glass fibers with an aqueous binder
composition comprising a substantially infinitely water-dilutable or
dispersible thermosetting esterification reaction adduct of a monomeric
polycarboxylic acid component and a monomeric polyol component,
wherein at least one of the monomeric polycarboxylic acid component and
the monomeric polyol component has an average functionality of at least 2.2
and wherein said adduct has residual carboxylic and hydroxyl groups and an
acid number of 100 or above, and (2) heating said aqueous binder
composition at an elevated temperature sufficient to effect cure.
The Examiner relies upon the following reference as evidence of
obviousness:
Arkens US 6,221,973 B1 Apr. 24, 2001
Appellants' claimed invention is directed to an aqueous binder
composition for making glass fiber products, and a method for binding
together glass fibers using the binder composition. The binder composition
comprises a reaction adduct of a monomeric polycarboxylic acid component
and a monomeric polyol component. The method entails contacting the
glass fibers with the adduct and then heating the binder composition at a
sufficient temperature to cure it.
The appealed claims 1 and 4-27 stand rejected under 35 U.S.C.
§ 103(a) as being unpatentable over Arkens.
