PROCESS FOR PRODUCTION OF SOLUABLE IN WATER CYCLODEXTRIN POLIMERS WITH LOW SALT-CONTENT

Prepn. of condensn. prods. of low salt content between substitd. cyclodextrines and epoxy cpds. in the presence of insol. basic polyelectrolytes. The latter is added to the otherwise customery aq. basic reaction mix at 10-600 wt.% (based on cyclodextrine). Opt., the cyclodextrine soln. is also passe...

Zusammenfassung:Prepn. of condensn. prods. of low salt content between substitd. cyclodextrines and epoxy cpds. in the presence of insol. basic polyelectrolytes. The latter is added to the otherwise customery aq. basic reaction mix at 10-600 wt.% (based on cyclodextrine). Opt., the cyclodextrine soln. is also passed consecutively through ion exchange columns in the H+ and OH- forms respectively.
