Poly(N-acryloxysuccinimide)(PNAS)was synthesized by atom transfer radical polymerization(ATRP) with 2-hydroxyethyl-2-bromoisobutyrate(HEBriB)／CuBr／2

2’bipyridine(bpy)as the initiation system．Its molecular weights can he predicted from the molar ratio of NAS／HEBriB in feed and the conversion．N-oxysuccinimide(NS)groups in PNAS are very active

and can be easily substituted by anmino compounds

such as butylamine

etc．So PNAS is used as precursor in preparation of conductive polymers．The polyaerylimide containing tetraaniline(PAA-NH(PhNH)3Ph)was successively prepared by the reaction of PNAS with amine capped tetraaniline(NH2(PhNH)3Ph)at 50℃ for 24 h．The substitution reaction efficiency is determined by the reaction temperature and the feed ratio of NS units to amine capped tetraaniline．When the substitution reaction was carried out at 50℃ with a molar ratio of NS／tetranniline 1：3．1H-NMR and FT-IR spectra of the product showed that the NS units in PNAS were substituted almost completely．While

only 10％ NS Was substituted at room temperature using the same feed ratio．The cyclic voltammetry measurements of the product showed two oxidation peaks at 0．4 and 0．62V．This provides a new routeto synthesize conductive polymers with aniline oligomers as side chains．
