Abstract
The invention relates to telechelic polymers based on radically polymerized, ethylenically unsaturated monomers which are obtained by polymerization by means of thiuram disulfides and dithiocarbamates, which have one or several additional functional reactive groups in addition to the carbamate group. The invention furthermore relates to the manufacture of the said type of telechelic polymers and to the use thereof, for example, as reactive precursors in higher-polymer linear or cross-linked products, especially as components of aqueous solutions, emulsions, dispersions, and suspensions for the preparation of coatings.
