Appeal No. 95-1079
Application 08/037,192
The Claimed Subject Matter
The claims on appeal are directed to a process for preparing
a suspension of submicron size polymeric particles for use as
powder coatings or in toner compositions. Claims 1 and 35 are
illustrative of the claimed subject matter:
1. A process for the preparation of a polymer
comprising: effecting bulk polymerization of a mixture
comprised of at least one monomer, a free radical
polymerization initiator, and a stable free radical
agent until from about 10 to about 50 weight percent of
the monomer has been polymerized to form a bulk
polymerization product; optionally adding additional
free radical initiator to said bulk polymerization
product; optionally adding a colorant to said bulk
polymerization product; dispersing said bulk
polymerization product with a high shear mixer into
water containing a stabilizing component selected from
the group consisting of non-ionic and ionic water
soluble polymeric stabilizers to obtain a suspension of
particles or droplets comprised of said bulk
polymerization product with said particles having an
average diameter of from about 0.1 to about 10 microns;
and polymerizing the resulting bulk polymerization
product suspension in water to form said polymer.
35. A process for the preparation of polymeric
particles useful for powder coating which comprises:
effecting bulk polymerization of a mixture of at least
one monomer, a free radical polymerization initiator,
and a stable free radical agent until from about 10 to
about 50 weight percent of the monomer has been
polymerized; optionally adding additional free radical
initiator; optionally adding a colorant; dispersing
with a high shear mixer the aforementioned partially
rejected claim. See Section 608,01(n) of the Manual of Patent Examining
Procedure, 6th Edition, Rev. July 1996, page 600-61.
