STUDIES ON THE PHOTO-COPOLYMERIZATION OF (4-VP)2 ZnCl2 WITH ELECTRON-DONATING MONOMERS
4-乙烯基吡啶-氯化锌络合物与电子给体单体光照下共聚合研究

The photo-induced copolymerization of the complex of 4-vinylpyridine and ZnCl2 (4-VP)2ZnCl2 (M1) as an electron-accepting monomer with the electron-donating monomer styrene (M2) was studied under the irradiation at 365 nm. The charge-transfer complex between them absorbs the light and then produces initiating radicals. The reactivity ratios were measured to be r1=2.04 and r2=0.24. The effect of the polarity of the solvents on the copolymerization and the photo-induced copolymerization of (4-VP)2 ZnCl2 with other electron-donating monomers were also investigated.
