A new way to prepare PMMA contain lead salt was presented.This work firstly prepares the material by microemulsion polymerization.The ability of anti-radiation,transmittance ratio and glass transition temperature(T_g)of the material was characterized.The anti-radiation ability is enhanced with the increasing of lead salt content and the thickness of the material.The transmittance ratio decreased with the content of the lead salt.The glass transition temperature of the material is increased with the lead salt content of the organic glass.
