Özet

Photopolymerization is one of the remarkable polymerization technique due to ambient polymerization temperature and also high rates of polymerization [1]. There are two types of photoinitiation mechanism, which are photofragmentation (Type I) and hydrogen abstraction chromophores (Type II) [2,3]. Poly(2-vinylpyridine) has a great potential as an adsorbant resin to remove pollutants from aquous solutions because of hydrophilic properties [4]. In this study 2-vinylpyridine was polymerized by photopolymerization by Type I photoinitiator. Benzoyl peroxide (BPO) and Benzoin (BN) were used as a Type I photoinitiator, dry tetrahydrofuran (THF) was used as solvent during polymerization. Initiator was placed into quartz tube and applied vacuum. After that, THF and monomer were added into the tube under N2 atmosphere. Photopolymerization occurred in 360 nm wavelenght for BPO and 310 nm for BN (Figure 1). The contains of the tube was dissolved in methanol when polymerization is over. Polymer solution was precipitated in diethylether and washed three times with ether. NMR and IR spectrums were obtained.
