Branched Polystyrene with High Reflex Index Synthesized from Selenium-Mediated Polymerization
In this article, the polymerization behavior has been investigated utilizing phenyl(4-vinylbenzyl)selane (PVBS) as an inimer under ultraviolet irradiation. Corresponding copolymers and homopolymers were synthesized by copolymerization PVBS with styrene and homopolymerization itself. The branching factors (g) of these branched polymers were characterized along with the polymerization conditions. Moreover, the results showed that the obtained polymers' refractive index (RI) can be enhanced by the introducing of selenium element. The results also indicated that the RI of obtained polymers could be adjusted extendedly by changing selenium content in them. (c) 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
