ABSTRACT:
Disclosed is a process for producing a styrene-based polymer having syndiotactic configuration, which comprises continuously polymerizing styrene or styrene-based derivatives in a self-cleaning type reactor, while providing a sufficient shearing force to maintain a polydispersive state at a temperature of not more than 120.degree. C.
According to the present invention, a styrene-based polymer having syndiotactic configuration can be produced efficiently and continuously, without adhesion of the polymer to the reactor and agitation blades.
