Appeal No. 1999-1279
Application 08/802,294
Regarding polymeric diol component (ii) in the
appellants’ claim 1, the examiner argues that St. Clair
discloses at columns 5 to 6 that polymeric diols, such as
polyether diols, can be included in the composition (answer,
page 3). The appellants argue that columns 5 to 6 of St.
Claire disclose diols which fall within the scope of their
chain extender component (iv) (specification, page 5, line 22
- page 6, line 2), but do not disclose polymeric diols (reply
brief, page 2). The diols disclosed in columns 5 to 6 of St.
Clair are “ethylene glycol, propylene glycol, butane diol,
hexane diol and the like” (col. 6, lines 2-3). The examiner
has not pointed out, and we do not find, where polymeric diols
are disclosed.
The examiner also relies upon Baack (col. 5, lines 21-24)
for a disclosure of polymeric diols (answer, page 4). Baack,
however, is directed toward the use of a monohydroxylated
polybutadiene as a reactive plasticizer in the preparation of
solid or foam polyurethanes from polyisocyanates and polyols
