| Abstract: | The photopolymerization of acrylonitrile (AN) initiated with triphenyl phosphine (TPP) has been studied. The kinetic equation was determined to be Rp = K AN]1.49 TPP]0.47 with the overall energy of polymerization (Ea) as 6.16 kcal/mole. Through the fluorescence spectra studies and Stern-Volmer equation analysis, the exciplex formation between the TPP and AN monomer and its initiation mechanism have been proposed tentatively. |
