Abstract
AbstractThe polymerization initiating activity of carbon black N220, unmodified as well as modified by pretreatment with various protonic and aprotonic acids has been examined in regards to N‐vinylcarbazole polymerization. The physico‐chemical characteristics of the polymer obtained by these catalyst systems have been investigated by I.R., X‐ray, 1H‐NMR, 13C‐NMR, gel permeation chromatography and thermal analysis measurements. Under certain conditions the resultant polymer shows some partial insolubility in methylethylketone. Contrary to the usual belief, this is not due to any stereochemical difference between the polymeric entities as observed by 13C‐NMR spectrum analysis of the methylethylketone insoluble fraction of the polymer.
