摘要

受电子单体4-乙烯基吡啶-氯化锌络合物(4-VP)2ZnCl2(M1)可以和电子给体单体如苯乙烯(M2)在365nm光照下共聚合。聚合是二者形成的基态电荷转移复合物(CTC)吸收光后产生自由基引发的。测得竞聚率为r1=2.04

r2=0.23。对溶剂极性的影响和(4-VP)2Znal2与其它电子给体单体光照下共聚合也作了研究。

Abstract

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 mono-mers were also investigated.
