ABSTRACT:
The present invention relates to a method for the preparation of purified elastomers prepared by emulsion polymerization, wherein the level of impurity is reduced by up to 99 wt. %, expressed in terms of the unpurified elastomer. The present invention also relates to elastomers which can be obtained by the method according to the present invention, to the use of the elastomers for the production of all types of products, and to the product which is produced by processing the elastomer which can be obtained by the method according to the present invention.
