examiner’s refusal to allow claims 8 through 14 which are all
the claims in the application.
THE INVENTION
The invention is directed to an apparatus comprising a
polymerization reactor. The apparatus contains means for
providing monomer and catalyst to said polymerization reactor
and means for removing reaction effluent containing polymer
and unreacted monomer from said polymerization reactor.
Outlets are provided for two flash separation means. The
apparatus contains a first flash separation means which
receives a major portion of reaction effluent. The flash
separation means separates monomer and polymer at a pressure
above about 100 psig. The apparatus further contains a second
flash separation means for receiving a minor portion of
reaction effluent. The second flash separation means
separates additional monomer and polymer at a pressure below
75 psig. Separated monomer from the second flash means is
analyzed. The monomer which is analyzed produces a signal
representative of at least one condition in the polymerization
