A method and apparatus for disintegrating an elastomer is provided. The elastomer is moved across a base relative to a cutting tool and toward the cutting tool. The cutting tool has a cutting wedge, which has a cutting edge and a rake face adjacent to the cutting edge. After the cutting wedge comes into contact with the elastomer, the elastomer is first at least partially compressed only by the rake face between the rake face and the base before the cutting edge cuts through the elastomer. An elastic evasive movement of the elastomer is avoided because of the initial planar compression of the elastomer by the rake face. Thus, it is possible to cut off significantly thinner pieces from the elastomer.

Disclosed are systems and methods for producing a polymer dispersion based on polychloroprene, comprising steps of polymerizing chloroprene to polychloroprene, adding the polycholoprene dispersion to a stripper column, and removing chloroprene from the polychloroprene dispersion.
