The present invention relates to an apparatus for carrying out chemical and physical processes, wherein flowable substances are mixed together, comprising a vertical, cylindrical vessel with inlets and outlets, as well as a central shaft and radial agitator blades arranged on the said central shaft and extending close to the wall. In this context, viewed in the peripheral direction, the agitator blades are curved and are combined in pairs of agitator elements one above the other to form groups, the blades of one element of the group being curved in a radially concave manner and the blades of the other element being curved in a radially convex manner.

Segmented agitator reactor

A process peroxidically treats olefin polymers with di-tert-butyl peroxide in an extruder. The olefin polymers together with di-tert-butyl peroxide under an inert gas are fed to an extruder. The olefin polymers are used in a finely divided form at from 55 to 110&deg; C. The use of peroxidically treated olefin polymers for producing moldings, fibers, films or nonwoven spunbond fabrics is described, as is a process for producing moldings, fibers, films or nonwoven spunbond fabrics.
