Abstract
Disclosed herein is a system for solution polymerization comprising a reactor system that is operative to receive a monomer and to react the monomer to form a polymer; a plurality of devolatilization vessels located downstream of the reactor system, where each devolatilization vessel operates at a lower pressure than the preceding devolatilization vessel; and a heat exchanger disposed between two devolatilization vessels and in fluid communication with them, where the heat exchanger has an inlet port temperature of 100° C. to 230° C., an outlet port temperature of 200° C. to 300° C., an inlet port pressure of 35 to 250 kgf/cm2 and an outlet port pressure of 20 to 200 kgf/cm2; and wherein the polymer solution remains in a single phase during its residence in the heat exchanger.
