| Abstract: | The polymerization of acrylamide (AAm) initiated by the combination of N-(N', N'-dimethylaminomethylene)methacrylamide (DMAMMA) or N, N,-dimethylaminoethyl methacry-late with potassium persulfate were studied kinetically. The rate equation for the AAm polymerization initiated by the above initiation systems were given asRp- KpAAm]K2S2O8]1/2DMAMMA]1/2 Rp=KpAAm]K2S2O8]1/2DMAEMA]1/2 respectively. The overall activation energies for the above polymerization were determined to be 8.7 Kcal/mol and 9.2 Kcal/mol respectively. The UV analysis for the PAAm initiated by the above initiation systema showed that the polymerizable amines,DMAMMA and DMAEMA notonly joined the redox initiation but also incorprated into the AAm polymer chains. The super high molecule weight,107of PAAm were obtained by using these initiation systems. |
