Appeal No. 96-1781
Application 08/389,521
amended after final rejection. These are all of the claims
remaining in the application.
THE INVENTION
Appellants’ claimed invention is directed toward a method
for making a water dispersion of a crosslinkable epoxidized
polydiene block polymer composition by dispersing in a mixture
of water and a nonionic or anionic surfactant having a
volatile cation, by use of a high shear mixer/emulsifier, a
mixture of an epoxidized block polymer and a compatible
aminoplast. Claim 11 is illustrative and reads as follows:
11. A process for making a water dispersion of a
crosslinkable epoxidized polydiene block polymer composition
which comprises:
(a) making a mixture of a surfactant which is nonionic or
anionic and has a volatile cation and water,
(b) adding a mixture of an epoxidized block polymer
having a weight average molecular weight of from 2000 to
3,000,000 and a compatible aminoplast to the surfactant/water
mixture, and
(c) dispersing the polymer/aminoplast mixture in the
surfactant/water mixture by mixing with a high shear
mixer/emulsifier.
