Abstract:

Polystyrenes with epoxy pendent groups were synthesized via atom transfer radical polymerization (ATRP). First, 4-(2, 3-epoxypropoxyl) benzaldehyde (EBD) was obtained by reaction of 4-hydroxy benzaldehyde and epichlorohydrin. Then, the Wittig reaction was carried out to convert EBD to styryl glycidyl ether (SGE). Finally, the polystyrenes with epoxy pendant groups were obtained by the SGE ATRP, which had controlled molecular weight and narrow molecular weight distribution.

Key words: atom transfer radical polymerization, ATRP;  epoxy pendant group; Wittig reaction
