Abstract
In a process for treating viscous products, especially for performing polymerization processes, especially for homo- or copolymerizing thermoplastics and elastomers, wherein monomer(s) and/or catalysts and/or initiators are added to a backmixed mixing kneader, especially with a length/diameter ratio of 0.5-3.5, heat is supplied to the product which is backmixed with already reacted product and the reacted product is removed from the mixing kneader, the product in the mixing kneader shall be heated up to its boiling temperature, portions of the product shall be evaporated and exothermicity of the product shall be absorbed by evaporative cooling.
