Abstract: Kinetic study of acrylamide (AAM) polymerization was carried out with persulfate-pyrroli-dine(PyD) system as the initiator and revealed that PyDis an accelerator for acrylamide polymerization.The initial free radicals of persulfate-PyDsystem was studied by spin trapping technique and ESRspectrum.The result confirms that the pyrrolidinyl free radical is one of the primary free radicals responsible for AAMpolymerization.
