STUDIES ON THE KINETICS OF VINYL PHOTOPOLYMERIZATION INITIATED BY CONDENSED AROMATIC HYDROCARBON-ANILINE SYSTEMS*
摘要:
The photopolymerization of acrylonitrile and methyl methacrylate initiated by condensed aro-matic hydrocarbon-aniline systenis was studied at 25℃ under irradiation of 365 nm wavelengthlight. From kinetic data the monomer exponent has been measured to be 1.1. Within the concen-tration of 10-4—10-3M, the aromatic hydrocarbon exponents changrd from 0.30 to 0.40, depedingon the values of molar extinction coefficient of the hydrocarbons at 365 nm (ε365). The greater theε365, the Iower the exponents.The aniline exponents were measured to be in the range of 0.30—0.45.The aromatic hydrocarbon-aniline systems with the lower aniline exponent showed a lower ratio of the fluorescence quenching of the hydrocarbon by aniline and by the monomer.
