Abstract: Polyvinyl acetate (PVAc) was synthesized with benzoyl peroxide (BPO) as initiator and methanol as solvent.The effects of the amounts of initiator and methanol and the reaction time on conversion and solid content were studied.The adhesive performance of polymers was also measured.In addition,the europium complex of PVAc (PVAc-Eu) was synthesized using PVAc as polymer ligand,and the structures of ligand and complex were characterized by IR spectroscopy.The luminescent and thermal properties of complex were also studied.The results show that,the optimized conditions for polymerization are as follows:methanol is in an amount corresponding to 11.9% of the volume of monomer,the dosage of initiator is 0.19 g,0.5% of mass initiator ratio to monomer and the reaction time is 3 hours,Using 508 nm as excitation wavelength,the fluorescence spectrum of the complex has a characteristic absorption peak of europium at 612 nm.Thermogravimetric (TG) experiments show that the initial thermal decomposition temperature of PVAc and PVAc-Eu are 300 ℃ and 86 ℃,respectively.
