Abstract
A liquid phase, powder bed polymerization process for preparing syndiotactic polymers of vinylaromatic monomers comprising: PA1 A) continuously introducing one or more vinylaromatic monomers and one or more catalyst systems to a horizontally disposed, continuously agitated, cylindrically shaped reactor containing a particulated solid, the contents of which are maintained in an agitated state at a Froude Number in the range from 0.1 to 10, and PA1 B) continuously removing polymerized product therefrom.
