Bromine as an initiator for the oligomerization of vinylformamide (VFA)
Bromine was found to be an effective initiator for the cationically induced oligomerization of vinylformamide VFA). Oligomeric products with molecular weights between 200 and 1500 g/mol were obtained. The structures of the oligo(vinylformamides) (OVFA) were investigated by means of NMR spectroscopy, GPC, and MALDI-TOF-MS. The influence of the reaction temperature on yield, DP, and head group functionality of the obtained OVFA was investigated. When the 1:1 adduct of bromine with VFA was used as initiator at 253 K, also oligomeric products are obtained.
