Reactor for continuous mass polymerization of alkenylaromatic monomers comprising a vertically oriented cylindrical chamber, means to cool at least the lower portion of the chamber, and agitating means comprising a plurality of integral circular disks positioned in vertically spaced relationship along a rotating vertical central shaft, each disk having attached at spaced intervals about its circumference a plurality of radially extending flat blade members. The blade members on the lowermost disk are vertically oriented, whereas the blades on the remaining disks are angularly displaced about their horizontal axes.
