Motionless mixers for the design of multitubular polymerization reactors

Exptl. investigations of the thermal bulk polymn. of styrene (I) in pilot plants of different sizes were done. Each pilot plant consisted of a tubular recycle reactor connected in series with a tubular reactor, both completely filled with Sulzer motionless mixers. Kinetic, reactor, and viscosity models were verified at I conversions ?96%, temps. ?210 Deg, and polystyrene mol. wts. ?360,000. Scale-up studies were done which confirmed that multitubular reactors of special design could be applied for industrial polymn. processes. [on SciFinder (R)]
