Synthesisof C-60-bonded polystyrene initiated with C60Cln/Ni(naph)(2)/P(Ph)(3)

摘要

A linear-shaped polystyrene with C-60 core was prepared with a novel initiator system, C60Cln (n average value is 20)/Ni(naph)(2)/P(Ph)(3), and T-p was 130 degrees C. The results of gel-permeation chromatography detected by UV detector and fluorescence spectrum of C-60-PSt demonstrated that C-60 was chemically bonded to polystyrene. The linear increasing of molecular weights (M-n,M-GPC) with conversion indicated that this novel initiator system had some characters of living polymerization. A bathochromic shift was found in the UV-vis spectra curves with increasing concentration of C-60-PSt in THF solution. (c) 2005 Wiley Periodicals, Inc.
