Appeal 1997-2375
Application 08/376,282
The claimed compositions cover silane "compositions"
comprising (A) a silane coupling agent and (B) inter alia a
tris(silylorgano)amine ("amine") having the general formula
[(RO) SiR ] N.1
3 3
Jex describes, inter alia, compounds which fall within
the scope of applicant's "amine" which are said to be useful
"as finishes for fibrous glass materials prior to
the preparation of reinforced plastics therefrom" (col. 1,
lines 38-39).
Plueddemann describes compositions comprising (A) a
silane coupling agent and (B) a disilyl crosslinker having the
formula
(RO) SiR'Si(OR)
3 3
(col. 1, lines 49-55), where RO is a hydrolyzable group. The
Plueddemann compositions are said to be useful as "primers"
(col. 1, line 64) and for pretreating particulate fillers
before compounding (col. 2, lines 1-2).
The examiner found that the utility of the Jex amine and
the Plueddemann compositions were the same. Based on that
