Synthesis and Solution Properties of the Photo-Sensitive Telechelic Polymer——Coumarin-Containing Poly(4-vinylpyridine)
摘要
Abstract
A novel photo-sensitive telechelic polymer-coumarin-containing poly(4-vinylpyridine) (CP4VP) was prepared using 4-vinylpyridine as a monomer, azodiiso-butyronile (AIBN) as an initiator, and coumarin-containing disulfides (C-S-S-C) as a chain transfer agent in the presence of tributylphosphine (Bu3P)/H20.The polymer was characterized by Fourier transform infrared (FTIR) spectroscopy, 1H nuclear magnetic resonance (1H-NMR), and gel permeation chromatography (GPC).We found that the telechelic polymer can form polymer micelles in aqueous solutions at various pH values (pH=3-6).Additionally, when lowering the acidity of the aqueous solution, the polymer micelles gradually compacted and the degree of coumarin photo-dimerization decreased initially and then increased within a similar irradiation time.关键词
