People paid more attention to transparent resins because of the excellent properties of the materials such as lightness, impact resistance, and processability. With the extensive usage of various radiation, there has a great interest in the preparation of radio-protective materials, especially in the study of the transparent radio-protective polymer. Most radio-protective resins are usually prepared with dispensing a metal oxide into the polymer, but the metal-containing polymer has poor strength and hardness. Also, the metal oxide is easy to dissipate from the materials, which will pollute the environment. Introducing metal ion to polymer chains can mend the shortcoming above mentioned, and improve some physical properties of polymer materials. In the present paper, we introduced lead ion into the polymer chains of styrene to prepare a series of Pb~(2+)-containing transparent resins, and studied the properties of the optical resins.
