Abstract

This study concerns the synthesis of C~60~‐capped vinyl ether (VE) oligomers with well‐defined structure by living cationic polymerization technique. The VE oligomers bearing C~60~ at the chain end were prepared by addition reaction between monoocynylfulleride anions and living cationic VE oligomers. Living oligo(isobutyl vinyl ether) (IBVE) and oligo(methyl vinyl ether) (MVE) were synthesized using CH~3~CH(OiBu)Cl/ZnI~2~ as initiating system. The C~60~‐capped VE oligomers were obtained as dark brown gummy solid in 28% for IBVE and 34% for MVE. The UV/VIS and ^13^C NMR spectra indicated the formation of C~60~‐capped oligomers via 1,2‐addition reaction. It was also found that the films of blends of C~60~‐capped oligomers with poly(IBVE) and polystyrene (5 wt.‐% C~60~) are homogeneous on a micron scale and transparent, resulting from a good dispersion of C~60~ in the polymer matrix.
