ABSTRACT:
A process for continuously producing a styrene-based polymer having high syndiotactic configuration which comprises continuously introducing a styrene-based monomer into a reactor and polymerizing to while adjusting the amount of the polymer produced in the reactor to at least 10% by weight of the total amount of the unreacted styrene-based monomer and the polymer.
According to the present invention, the styrene-based polymer with high syndiotactic configuration is effectively produced with small power consumption.
