content thereof. Specifically, the terminology "wherein the
unreacted
1-olefin is present in a percentage to cause sufficient
copolymer to dissolve in a light phase defined below so as to
give rise to plugging of equipment downstream of a high
pressure separation” as recited in claim 19 is inconsistent
with the other claim 19 requirement that “said fresh supply of
ethylene reduces the concentration of 1-olefin in the light
phase, and thus reduces the solubility of the copolymer in the
light phase.” This is so since the fresh supply of ethylene
is introduced to the polymerization reaction mixture during
the high pressure separation in which the light phase is
obtained as set forth in claim 19. Thus, there would appear
to be only one light phase
obtained from that high pressure separation. That obtained
light phase would have a particular percentage of 1-olefin
therein and a particular amount of copolymer dissolved
therein.
