Appeal No. 95-0878
Application 07/921,820
Appellants’] specification teaches polyoxazolines it thus does not enable linear compounds
as shown in claims 3, 21 and 22 called polyoxazolines as in claim 1 and it is the Examiner’s
position [that] the use [of] polyoxazoline is incorrect. [Answer: p. 3.]
The examiner references page 12 of JP 4-202345 which describes a polymer that contains oxazoline
groups as follows:
The polymer (B) that contains oxazoline groups utilized in this invention is
preferably a polymer obtained by polymerizing the addition polymerization oxa-zoline
expressed by the general formula
(wherein R , R , R , [and] R are hydrogen, halogen, alkyl, aralkyl, phenyl or substituted1 2 3 4
phenyl groups, separately and respectively, while R is acyclic organic groups that possess
5
addition polymerization unsaturated bonds) and at least one kind of other monomers (b),
as needed.
The addition polymerization oxazoline (a) utilized in this invention is expressed by
the above mentioned general formula (1), specific examples thereof may include 2-vinyl-2-
oxazoline, 2-vinyl-4-methyl-2-oxazoline, 2-vinyl-5-methyl-2-oxazoline, 2-isopropenyl-2-
oxazoline, 2-isopropenyl-4-methyl-2-oxazoline, 2-isopropenyl-5-ethyl-2-oxazoline, etc.,
whereof 1, 2 or more kinds may be used as a mix.
Appellants argue that the formulas set forth in claims 3 and 21 are illustrated on page 7, lines 1-8 of their
specification and that the preparation of the polymers are set forth on page 8, lines 6-17 of the specification.
In particular, appellants disclose that
