| Abstract: | The photopolymerization of acrylonitrile sensitized by N-methyl-N-(2-methacryloyloxye-thyl)aniline (MEMA) was studied kinetically. The photopolymerization rate of AN in DMF by using MEMA as sensitizer is proportional to 0.32 th power of MEMA concentration and 1.20 th power of AN concentration. The overall activation energy for the polymerization was found to be 4.82 Kcal/Mol. From the fluorescence analysis of obtained polyacrylonitrile sensitized by MEMA, it was confirmed that MEMA not only joined the initiation but also enrered into the polyacrylonitrile chains. The initiation mechanism was proposed tentatively. |
