The invention relates to processes and plants for continuous solution
polymerization. Such plant and processes include a pressure source, a
polymerization reactor, downstream of said pressure source, pressure
let-down device, downstream of said polymerization reactor, and a
separator, downstream of said pressure let-down device, wherein said
pressure source is sufficient to provide pressure to said reaction mixture
during operation of said process plant to produce a single-phase liquid
reaction mixture in said reactor and a two-phase liquid-liquid reaction
mixture in said separator in the absence of an additional pressure source
between said reactor and said separator.
