ABSTRACT:
There are provided polymers containing amido-thiolate groups. These are produced by a nuceophilic substitution of polymers containing chlorine, and the resulting polymers have a pronounced hydrophylic character. There is also provided a process for the production of these starting with polymers which contain chlorine in the polymeric backbone or in side chains.
