queous solution polymerization of acrylamide (AAm) was demonstrated by using initiation system consisting of N-methacryloyl-N '-pyrimidinopiperazine (MPMP ) and persulfate (KPS). The polymerization rate equation was obtained to beRp = Kp[MPMP]1/2 [KPS]1/2 [AAm]1.0The overall activation energy for the polymerization was calculated by Arrhenius quation to be Ea= 5.6 KJ/mol. The redox nature for the polymerization was clarified. A super high molecular weight up to 107 of PAAm was obtained by using this initiation system. From the fluorescent analysis
it was confirmed that MPMP not only acted as a component of the redox system
but also entered into the acrylamide polymer chains.
