Abstract
The influence of the kind of initiating system and the addition of a c rown ether on the anionic polymerization of oxiranes with a carbazoyl substituent is described. Potassium alkalide, potassium tert-butoxide and potassium hydride were used as initiators. Selecting a suitable in itiator and crown ether concentration, carbazolyl-containing polymers with polymerization degrees from 4 to 60 can be produced. Using a susp ension of potassium hydride in tetrahydrofuran, polymers with relative ly high molar masses were obtained.
