rejections, we make reference to the Answer (mailed May 1,
2006) for the Examiner’s reasoning in support of the
rejections, and to the Briefs (filed February 10, 2006 and May
25, 2006) for the Appellants’ arguments thereagainst.
OPINION
Appellants’ invention relates to a polyurethane-modified
addition copolymer prepared by free radical copolymerization of
an olefinically unsaturated monomer in the presence of the
reaction product of (A) an addition copolymer and (B) a
polyisocyanate. Representative claim 1, as presented in the
Brief, appears below:
1. A polyurethane-modified addition copolymer prepared
by free radically (co)polymerizing at least one
olefinically unsaturated monomer (a) in an aqueous or
nonaqueous medium comprising the reaction product (A/B) of
(A) at least one addition copolymer containing on
average per molecule at least 0.1 isocyanate-reactive
functional groups prepared by free-radical
copolymerization in an aqueous medium or nonaqueous medium
of at least
a) at least one olefinically unsaturated monomer
and
b) at least one olefinically unsaturated monomer
different than the olefinically unsaturated
monomer (a) and of the general formula I
