摘要

Abstract

The polymerization of acrylamide was carried out in H2O-DMF (3:1 v/v) solution using eerie ion (eerie ammonium nitrate

CAN) as initiator. It was found that the presence of 4

4'-diacetaminodiphenylmethane (DAADPM) could promote the polymerization and increase the rate of polymerization. The overall activation energy and rate equation of acrylamide polymerization initiated with eerie ion/DAADPM system were determined respectively. From IR spectrum end-group analysis of polyacrylonitrile (PAN) prepared by solution polymerization of AN using CAN/DAADPM system as initiator

it revealed the presence of DAADPM end-group in the polymer. Accordingly

the initiation step includes the addition of DAADPM radical to monomer and forms the end-group of polymers.
