A method for producing a lead containing monomer composition comprising reacting a mixture comprising (1) at least one monomer selected from the group consisting of alkyl methacrylate having 1-4 carbon atoms in an alkyl group, hydroxyalkyl acrylate, hydroxyalkyl methacrylate and styrene, (2) acrylic or methacrylic acid, (3) an organic acid having the general formula: R1COOH, wherein R1 is hydrocarbon residue having 5-20 carbon atoms and optionally (4) an organic acid having the general formula: R2COOH, wherein R2 is hydrocarbon residue having 2-4 carbon atoms with lead monoxide. The composition is polymerized to obtain a radiation shielding polymer. |
