Abstract
Method for the shortstopping of polymerizations of conjugated dienes possibly mixed with vinyl-substituted aromatic products in a radicalic emulsion polymerization process using a redox initiator, in particular radicalic emulsion polymerizations of butadiene possibly mixed with styrene or acrylonitrile, a method which enables the production of polymers without nitrosamines (NA) and/or their precursors.
