This paper reports a new method of the synthesis of terminal naphthalene-la
beled and carbazole-labeled PP. This method involves the synthesis of a bor
ane-terminated PP intermediate and the selective oxidation of this intermed
iate to form stable polymeric radicals which then react with maleic anhydri
de or N-vinylcarbazole producing maleic anhydride terminated PP and termina
l carbazole-labeled PP, respectively. Naphthalene terminated PP was prepare
d by reaction of maleic anhydride terminated PP with 1-naphthylmethylamine.
Infrared, H-1 NMR, UV and fluorescence measurements all proved the couplin
g of the chromophore groups to the PP chains. GPC results showed that no de
tectable cross-linking or degradation appeared during the functionalization
of PP. The chromophoro-labeled polymers were used as probes to study the p
enetration of oligomeric PP chains into labeled PP particles. The changes o
f fluorescence spectra showed that chromophore groups in amorphous phase we
re diluted upon addition of oligomeric PP.
