Process for producing styrene-based polymers and apparatus for producing said polymers.

摘要

A process for producing styrene-based polymers, which comprises polymerization styrene or styrene derivatives at a temperature of not higher than 110 DEG C while applying sufficient shearing force to maintain a polydispersive state, so as to make a substantially solid-state polydispersoid of the product and reaction apparatus suitable fcr performing said process. According to the process and apparatus, when polymerizing styrene or styrene derivatives, styrene-based polymers having mainly syndiotactic configuration with uniform particle size can be obtained efficiently without adhesion of scale to the reaction tank or agitating blades, and moreover, it is possible to control the particle size of polymers, and post-treatment and other treatments becomes easier.
