Claims9
A polymer of M.sub.n of 300-100,000 containing a carbon-to-carbon backbone and characterized by the presence of at least one group of the formula ##STR14## wherein R', R", R'" are hydrogen, or alkyl, aralkyl, aryl, alkaryl, or cycloalkyl hydrocarbon groups or electron-withdrawing groups selected from the group consisting of --SO.sub.3 H, --CX.sub.3, and --COOR, wherein R is alkyl, alkenyl, alkynyl, aryl, aralkyl or cycloalkyl, at least one of R', R", and R'" being an electron-withdrawing group;
- R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are hydrogen or hydrocarbon, at least one of R.sub.1 through R.sub.5 being a portion of the polymer backbone;
- and X is halogen.
