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.
Claims6
A modified polymer produced by nucleophilic substitution of a chlorinated polymer selected from the group consisting of polyvinyl chloride and chlorinated polyethylene, having chlorine atoms susceptible to nucleophilic substitution, wherein a portion of said susceptible chlorine atoms have been substituted by a group of the formula:
- ##STR8## where n is an integer of 1 to 20 and R.sub.1, R.sub.2 are each selected from the group consisting of hydrogen, alkyl, polyamide and polyamino acid groups.
