摘要
N-(N′,N′-二甲氨基亚甲基)甲基丙烯酰胺、甲基丙烯酸N,N二甲氨基乙酯、可聚合叔胺、氧化还原引发体系。
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- Kp[AAm][K2S2O8]1/2[DMAMMA]1/2 Rp=Kp[AAm][K2S2O8]1/2[DMAEMA]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 not only joined the redox initiation but also incorporated into the AAm polymer chains. The super high molecule weight, 107 of PAAm were obtained by using these initiation systems.
