We investigated the synthesis of polymer-bound iodonium salts with chl
oride as anion by polymer analogous reaction. The structure of polymer
s was determined with NMR-spectroscopy, MS-analysis as well as by mode
l substances. The polymers give transparent films on glass, they decom
posed during irradiation and eliminated HCl. The HCl-elimination in th
e films can be detected with indicators and also with potentiometric t
itration with AgNO3.
