Appeal No. 1996-2015
Application No. 08/181,539
second retaining means for retaining a continuous phase component comprising
a medium;
disperser means for forming a dispersion of said disperse phase component and
said continuous phase component, said disperser means comprising a stationary part
having an inner surface, a rotating part disposed within said stationary part having an
outer surface, said inner surface and said outer surface having substantially the same
shape and defining a space therebetween having a substantially uniform thickness in the
range of about 0.01 mm to about 5.0 mm, a uniform shear force generating field
disposed in said space;
first supplying means for supplying said disperse phase component from said
first retaining means to said shear force generating field at a constant rate;
second supplying means for supplying said continuous phase component from
said second retaining means to said shear force generating field at a constant rate, said
first and second means being independent whereby said disperse phase component and
said continuous phase component contact one another for the first time in said shear
force generating field;
polymerization means for polymerizing said dispersion; and
means for supplying said dispersion to said polymerization means.
Independent claims 32 and 33 recite the apparati of claims 28 and 29, respectively, except that the
stationary part is changed to a second rotating part.
