and the water-soluble porphyrin polymer of hemin-poly (
N
-vinylpyrrolidone) was obtained. The structure of the polymer was characterized using
1
H NMR
IR spectra and GPC chromatography. Meanwhile
the effect of dosage of initiator and ratio of the two monomers on the polymerization reaction was studied. The results showed that the copolymerization between vinyl group of hemin and N-vinylpyrrolidone occurred and a cross-linking copolymer was obtained.
