Application No. 07/658,878
pending in this application, have been withdrawn from further consideration under 37 C.F.R.
§ 1.142(b) as not readable on the elected invention. Claims 1 and 29 are illustrative:
1. A method of suspension polymerization of a monomeric composition to
produce uniformly sized particles having a narrow distribution, which method comprises
the steps of:
(a) retaining in independent vessels a disperse phase component including said
monomeric composition and a continuous phase component;
(b) supplying said disperse phase component and said continuous phase
component from their respective vessels simultaneously and continuously through
associated independent passageways into a uniform shear force generating field of a
disperser, said disperser including a stationary part having an inner surface and a tubular
rotating part having an outer surface, said rotating part being rotatably provided within
said stationary part, said inner surface and said outer surface having substantially the
same shape and defining a space therebetween having a substantially uniform thickness,
said uniform shear force generating field being provided in said space;
(c) applying shear force to said disperse phase component and said continuous
phase component in said shear force generating field to form a dispersion having
droplets of a desired size;
(d) removing said dispersion from said shear force generating field;
(e) introducing said dispersion into a polymerization vessel; and
(f) completing a polymerization reaction to produce uniformly sized particles
having a narrow distribution.
29. A method of suspension polymerization of a monomeric composition to
produce uniformly sized particles having a narrow distribution, which method comprises
the steps of:
(a) retaining in independent vessels a disperse phase component including said
monomeric composition and a continuous phase component;
(b) supplying said disperse phase component and said continuous phase
component from their respective vessels simultaneously and continuously through
associated independent passageways into a uniform shear force generating field of a
disperser, said disperser comprising a stationary part having a first circular surface and
