摘要
2-乙烯基萘与反丁烯二腈可以在365nm光照下共聚合,生成1:1交替共聚物。研究了聚合反应的引发机理,认为通过二者的基态电荷转移复合物受光激发和2-乙烯基萘的定域激发形成激发态复合物,其进一步反应生成1,4-双自由基,引发链增长。
The copolymerization of 2-vinylnaphthalene with fumaronitrile takes place under the irradiation of 365 nm to produce 1:1 alternating copolymer.The initiation mechanism was studied.The excited complex is formed from the excitation of the charge-transfer complex of the comonomers and the local excitation of 2-vinylnaphthalene and then collapses to 1,4-bira dical which will initiate the polymerization.
