Dibutyltin maleate (DBTM) was synthesized by the reaction of maleic anhydride with dibutyltin oxide in THF at 50℃ for 12h.The monomer was characterized to be monomeric which containing only one tin atom by ICP

FT IR and elemental analysis.Its copolymerization with VAc using AIBN or under the UV irridation was carried out.The CTC formation of DBTM with VAc was confirmed by absorption spectra.A typical alternative copolymer was obtained either by AIBN or upon UV irridation as maleic anhydride did.
